Re: VM Workshop -- was fantastic!
The suggestion of a June date will work better for me as well. I just returned from EAA Airventure, the largest aviation event in the world. It's always the last week of July in Oshkosh, WI.

I have another commitment for that weekend And thus it begins... ;-) For all the years I organized the Rexx Symposium, we would start out with a location, set a date that the greatest number of people could attend, canvass venues for availability prices, change the date to a less-optimal based on the canvass, lather, rinse, and repeat until we had the perfect compromise: everyone was equally unhappy. Invariably, the date of the Symposium was set by factors completely beyond our control. But it's nice to ask everyone what they would like, if only to show that you are trying to be accommodating. :-/ Until you've successfully pulled off an event such as the Workshop or the Symposium (both of which were notable for affordability) you have no idea how hard it is to make it happen. Even though I couldn't be there this year, I'm grateful to the organizers for the effort that went into reviving one of the more valuable conferences I attended back in the day. -Chip-

Re: Varsity Inn North South University Plaza - VM Workshop Hotels
Sadly, it's become common practice to trash competitors in reviews on most online sites. So much so that there are companies that will (for a fee) look for them and delete them for you. (For all I know, the trashing is being done for a fee as well.) Quite the opportunistic little eco-system. I travel a lot and stay at a variety of low- to mid-tier properties, albeit usually ones affiliated with national brands. I have never seen a bedbug, much less been bitten by one. And yes, I've stayed at hostel-grade properties in NYC, Chicago, and LA. You stay where your budget will allow. I think the whole hotel bedbug infestation publicity is blown out of proportion, but I could be wrong. -Chip- On 6/28/11 16:57 Len Diegel said: I just had a discussion with the manager at the Varsity Inn locations ($69/night).

Re: Sevice level
I don't see how any sort of meaningful number could be assigned to an entity to reflect COR service. Everyone will have their own. An RSU OTOH, floats everybody's boat to the same level, at least for a while. About the only thing you (IBM) could do is to add a flag that some service had been applied beyond the RSU (service level 801+ ?). I suppose you could assign each PTF a sequential number and use that to build a bit-string (1=applied, 0=not) and report a honkin' big hex value. ;-) Then, not only could you tell that extra-RSU service had been applied, but with a little effort you could tell exactly what. Hey, with VMSES/E in Rexx, it's all just a SMOP isn't it? :-)) -Chip- On 4/10/11 00:05 Alan Altmark said: Following up on Nick Harris' expectation to see a change to QUERY CPLEVEL after applying COR service to CP, I'd like to open a discussion on how folks perceive service levels.

For the sake of discussion, let us assert that: - We are talking about the running entity, not the copy of the entity on the build disk. - Unless there are specific pre-reqs or co-reqs, PTFs can be applied in any order or combination. - Each component (CP, CMS, DIRMAINT, RACF, SES, etc.) has its own service stream Regards, Alan z/VM and Linux on System z Consultant IBM System Lab Services and Training ibm.com/systems/services/labservices office: 607.429.3323 alan_altm...@us.ibm.com

Re: How can get the Week day ?
That's correct Ed, and WAD. Date('B') is intended for doing reliable
date arithmetic, not archeology. :-)
A consistent algorithm is more important to modern programmers than
hewing precisely to historical usage (were that even possible, given
the multiplicity of calendar schemes used in antiquity). Those who
assert that Jesus was born on a Monday have a few other errors to
explain first. Usually they are the ones who also delight in the UNIX
'cal 9 1752' special case.

Well, not quite, unless you're using a VERY non-ANSI-Standard version
of Rexx. :-)
Say Date('U',0,'B') -- 01/01/01
But you're right about the C for Century; it was always better to
think of it as the Roman numeral for 100. It still suffered from the
same boundary issues as the old Julian date, just not as frequently.
The fact is, Date('C') is not even legal at Rexx Language Level 4.00
(much less ANSI Standard) which has been around for quite a while now.
So the best option is to simply forget about the Date('C') option in

Re: Mandatory ESMs?
At the risk of ignoring his assertion about the length of this thread, Richard has provided the perfect opening for me to mention Open Object Rexx. :-) That's the Open Source evolution of IBM Object REXX, supported by a team of developers lead by Rick McGuire (an original developer of IBM OREXX), is freakishly powerful, and currently runs on every major platform (32/64-bit Windows, Mac, UNIX/Linux, looking into Android) -- except z/VM and Z/OS. Believe me, it's not for lack of desire, interest, or love of CMS. We simply don't have access to the necessary resources (hardware and wetware) in order to effect a proper port of the (predominately C/C++) code. If you would be interested in contributing in some way to the effort to port ooRexx to IBM's Flagship Operating System (and/or z/OS ;-) please go to the ooRexx website www.oorexx.com and contact the Project Manager, David Ashley.

Re: REXX that verify what MINIDISK is a file
Sergio, It's not clear to me why you are issuing the LISTFILE in the first place. Is that a necessary function of your (now named) VX EXEC, or is it left over from your initial attempt to determine which disk your EXEC was running from? If stacking the output of the LISTFILE is a necessary function of your EXEC, it really should be invoked _after_ you have verified that you are executing the right version of your EXEC in the first place. That would also make the DESBUF unnecessary when you find out you aren't. If the Rexx program you are running is VX EXEC, and the LISTFILE is left over from your initial attempt to discover which disk it is being executed from, then you should remove the LISTFILE and DESBUF commands. They are no longer necessary. The Rexx Parse Source command is all you need. Here is how I would have done it, using a slightly more sophisticated Parse template to avoid the Left() built-in function: /* VX EXEC - Do something necessary and useful */ Trace Results Parse Source . 'EXEC' fm +1 . If fm = 'X' Then Call NandUcode Say You are not executing from the 'X' disk!

Re: Rexx Question
That's because Value is a Rexx Built-in Function. A Rexx function doesn't
know (or care) if it was invoked as a function or Call'ed as a subroutine, as
long as it Return's a value of some sort. Thus,
Say Left('Rexx Rox',4)
is exactly equivalent to
Call Left 'Rexx Rox',4
Say Result
The purpose of the Symbol() BiF is to access the Rexx symbol table. Normally
the first argument is the symbol (variable name) itself, capitalized and quoted
to avoid indirect reference. If a second argument is specified, the symbol is
given the value indicated by the second argument. Regardless, the current value
of the symbol will be returned. Thus,
abc = Symbol('XYZ')
is exactly the same (except for speed) as
abc = xyz
and
abc = Symbol('XYZ','Rexx Rox')
is exactly equivalent to
abc = xyz
xyz = 'Rexx Rox'
Normally, one would code the statement you reference as:
curval = Value(zb123, lz99pe)
unless (as appears to be the case) the programmer is not interested in getting
back the current value of the symbol stored in the symbol 'ZB123', but merely
setting its value to the value contained in the symbol 'LZ99PE'.
In this case, it appears that the programmer is indirectly referencing another
symbol, and assigning it the value of the second symbol. It avoids an Interpret
instruction.

Re: How to work with hex in REXX
A lot of my students have the same problem so I explain it this way:
The x2y functions all take character strings. If that character string is a
valid value in the base indicated by the 'x' in the function name, it will be
converted into a string representation of that value (if possible) in the 'y' base.
A common problem is when you want to find the decimal equivalent of a hex value.
The temptation is mighty strong to code dec=X2D('2FC8'x). As soon as you
encode the hex value _as_a_hex_constant_ Rexx dutifully converts that string
into its internal representation, and that is the value that X2D() sees.
Basically, I tell them not to over-think the problem. It's simply string-in,
string-out, and the name tells you what Rexx expects and what he will return.
-Chip-
On 4/30/10 14:42 Kris Buelens said:
Often it is not obvious which x2y conversion function has to be used.

Therefore I wrote an XTOX EXEC that tries all REXX conversions and show
the result. It is part of

For example XTOX 56 displays:
C2D(56)=13622 =X'3133363232'
C2X(56)=3536=X'33353336'
D2C(56)=8 =X'38'
D2X(56)=38 =X'3338'
X2C(56)=V =X'56'
X2D(56)=86 =X'3836'
X2B(56)=01010110=X'3031303130313130'
B2X(56)=impossible

Try using the X2C REXX builtin function. For example,
String = X2c(PRK)
If the value of PRK will ever have a length different than 4 (which
seems to
be required by your logic), check the X2c documentation for the length
operand.

Re: Problem that is a blast from the past...
I'm sorry to rise to the bait, but the nearly universal misunderstanding of the MAKEBUF command is one of my sore spots. PEDANT There is absolutely nothing about MAKEBUF that provides any sort of separation of the records in the program stack. Successive reads from the stack will completely ignore any MAKEBUF point and happily continue to read records until the stack is empty, with no indication that a MAKEBUF point was passed. To ensure that no more records are read from the program stack than were placed there after a MAKEBUF, it is necessary to do a Rexx Queued() or SENTRIES command at the MAKEBUF point to determine how many records are already on the stack, and then remove no more than were added after the MAKEBUF. This essentially renders the MAKEBUF/DROPBUF superfluous. The ONLY thing that MAKEBUF does is to reset the FIFO pointer to equal the LIFO pointer. This is quite handy because it allows one to place a group of records on the top of the stack in FIFO order. Without MAKEBUF, this operation would require reading all the records off the stack, stacking the new records FIFO, then restacking FIFO the original records. The closest that MAKEBUF comes to a separate what you place in the stack from what is already there operation, is that if all of the records that were added to the program stack after a MAKEBUF command are not removed, the remaining records can be deleted with the appropriate DROPBUF. /PEDANT If at some point, CMS is given the benefit of multiple program stacks (as in the TSO/REXX environment) you could truly separate what you place in the stack from what is already there by placing the new records in a new stack. At that point, MAKEBUF and DROPBUF will become vestigial. TSO/REXX's NEWSTACK/DELSTACK commands and the ability to create a stack of stacks is what everyone seems to think MAKEBUF/DROPBUF provides. -Chip- On 9/15/09 15:49 Kris Buelens said: Yes, DROPBUF 0 would be even better, a MAKEBUF is not required in such a server I'd say: you'd use it to separate what you place in the stack from what is there already, but as you code DROPBUF 0, there is surely nothing anymore to separate your stuff from.

VM/370 R6 does have DCSS (DisContiguous Shared Segments IIRC) - Even without SEPP or BSEPP. But of course, contrary to modern VM systems (ie, VM/XA onward), these needed to be defined when the nucleus is built (via DMKSNT) - and space had to be allocated (that is, even though the space was allocated as PERM, you had to make sure no user MDISKs were sitting there) and formatted (through IPL FMT) especially for this purpose on a CP owned DASD. Note that VM/370 R6 is still being actively used as a learning tool by some individuals who aren't lucky enough to have access to a modern and up to date VM system - since it is the last VM release that was available as a no-charge SCP - and is also believed to be de-jure (although IANAL) public domain because of the lack of copyright statement and because it was release prior to the 1976 copyright laws. --Ivan

Re: REXX Date Function Help...Please
Yes, that was the intention of the ANSI Standard Committee's Y2K work. It is
not possible to convert from any of the ambiguous date formats. What should
Date('U', 'Tuesday', 'W') return?
Since the Julian format was defined to have only a two-digit year (yynnn) there
is no way to define an accurate equivalent date. And yes, we discussed sliding
windows and a number of other hacks and ultimately rejected them as dangerous.
One could get the wrong answer and not know it. We like the 'astonishment

Besides, as Bob has shown, there are several ways of accomplishing the

This is a minor problem in the overall scheme of things but I have noticed it occurring with greater frequency lately. It appears that sometimes members of a discussion list will initiate a new topic by simply replying to a recent posting and changing the 'Subject:' line.

Unfortunately for those of us who get and archive massive amounts of discussion list postings, this reply will appear to be a strand of the original discussion thread, despite the different 'Subject:' line.

The result is that such topic threads are now totally invisible when viewed in a threaded mail reader or file manager. And yes, I know that listserver archives are available but I do a lot of my work with custom Rexx tools on a local archive, or while offline.

Re: REXX DATE function
Well Steve, the rules are exactly as I stated them: Rexx is case-sensitive when
it regards data; it is case-insensitive only when it comes to how the Rexx code
itself is written.
It would be a greater stretch to assume that one built-in function (Date) would
behave differently from all the other BIFs in regard to case-sensitivity. And I
think you would have a hard time convincing IBM (or the rest of the Rexx
community for that matter) that only the Date() function should be changed to
disregard case. I have no doubt that such a change would raise the Astonishment
Factor significantly.
If it is that big of an issue, may I suggest that 'SET LANGUAGE UCENG' will
solve your problem, but you may find the cure is worse than the disease. :-)
As for improving the documentation to explicitly state that the output format of
Date('Normal'), and thus the input format for Date('Basedate',mydate,'Normal')
is in mixed case, there are two problems:
1. The documentation seems pretty complete to me already:
NORMAL -
date in the format: dd mon . This is the default (dd cannot have any
leading zeros or blanks; must have leading zeros but cannot have any
leading blanks). If the active language has an abbreviated form of the
month name, then it is used (for example, Jan, Feb, and so on). If Normal
is specified for input_date_format, the input_date must have the month
(mon) specified in American English (for example, Jan, Feb, Mar, and so
on).
2. The case is dependent on the SET LANGUAGE value (see Note 4).
One inescapable factor is that z/VM and z/OS are running embarrassingly ancient
versions of the Rexx interpreter, ones that are not even ANSI Standard compliant
over a decade after it was written. IBM gave Object REXX to the Rexx Language
Association to support and enhance it as an open-source project (see
http://sourceforge.net/projects/oorexx/).
The Open Object Rexx interpreter supports all the other major platforms
(Windows, UNIX/Linux/AIX, Mac) and is not only object-oriented, but has
caseless versions of those routines. Efforts to port the ooRexx code to VM
and/or TSO has stalled for lack of resources and expertise, not interest or
enthusiasm.
Perhaps you would care to help?

Re: REXX coding question.
Thank you, Richard. That is exactly what I was trying to illustrate. I'm a big fan of Rexx stems and PARSE, and regularly exploit their power. But there comes a time when one must eschew elegance (and perhaps some efficiency) on behalf of the poor schmuck who will need to read, understand, and/or modify your code later. Especially if that poor schmuck might be yourself. That is the why, of the eleven Fundamental Language Concepts of Rexx enumerated by Mike Cowlishaw (TRL, Part 1, Section 3) the very first is Readability. [Note to Original Poster: he also lists the use of mixed case code as the first of the five components of readability. There is no excuse for the readability of any Rexx program to be sacrificed on the alter of the 026 keypunch!] So, by all means, code your compound condition IF. But when your logic becomes convoluted and it misbehaves, Rexx allows you to restate your problem in a clearer way. If that means coding a Then Nop because positive logic in your compound condition makes it clearer what you are checking for, so be it. If coding If \Abbrev(...) gives you the same clarity (and more user input options) go for it. If coding Select ... When ...s lets you test multiple disparate conditions while avoiding nested If ... Then ... Else If ...s, Rexx is there for you. Precisely because Rexx has such expressive power it can, more than most other programming languages, reveal flaws in the problem solution before it ever gets to the execution step. Just look for statements that don't scan well in English. If your mother could read it verbatim and have some idea of what's going on, it's probably okay. One last point that no one mentioned to the OP: one of the joys of programming in Rexx is the ease with which debugging is accomplished. The _very_first_ thing I would have done in his situation would have been to insert a Trace ?I in front of the failing instruction. The output of an Intermediate trace would have made obvious the logical flaw in his IF instruction. With that, and there being no objection, I declare this thread closed.

2 _.OKAY . 2 _.PLEASE . 2 _.SURE . ,
4 phrase 2 _.phrase .
Say Should I do this?
Parse Upper Pull answer
If _.answer Then Say I will do it.
Else Say I will not do it.
Not that I am espousing this sort of programming (there is such a thing as
giving the user too many options) but the PARSE instruction packs quite a bit of
power and will usually perform multiple assignments faster than multiple
assignment statements.

Futhermore when coding SYMBOL('_.'answer) you will get a double

When symbol('_.answer')'VAR' then
With your SYMBOL() code, an answer like I GROVEL BEFORE YOU TO PERMIT
IT will be refused

Re: REXX coding question.
I'm afraid we're gonna have to cite you for a flagrant violation of DeMorgan's Law, Howard. ;-) In fairness, your problem is not caused by unfamiliarity with formal logic, but mere lack of clarity. If I might suggest an alternative so far overlooked: If \(Left(answer,1) = 'Y' | answer = 'YES') Then Do Say answer Say The wrong response has been entered etc This is logically equivalent and has the advantage of placing the comparisons in positive terms. Also, Left(foo,1) is equivalent to Substr(foo,1,1) and somewhat clearer as well. However, you are still stuck with the counter-intuitive IF NOT condition. So what's wrong with phrasing your question in the positive and taking the other leg of the If-Then-Else? If Left(answer,1) = 'Y' | answer = 'YES' Then Nop Else Do Say answer Say The wrong response has been entered etc Does that not make the intent of the code much clearer? -Chip- On 7/7/08 16:23 Howard Rifkind said: This is confusing me. The response to the variable 'answer' is a Y. Yet this portion of the code isn't working. Shouldn't the logic just fall thru because the response was a Y. IF SUBSTR(ANSWER,1,1) /= 'Y' | ANSWER /= 'YES' THEN DO SAY ANSWER SAY 'THE WRONG RESPONSE HAS BEEN ENTERED' SAY SAY 'PROCEDURE IS TERMINATING, PLEASE TRY AGAIN' EXIT END Thanks

The Getting Started with z/VM for Linux book is a good place to start. As to IBM classes, the reason that IBM doesn't offer many formal z/VM classes is that there isn't much demand. If folks want IBM to offer more classes, you need to contact IBM education folks. Speaking as the instructor of the upcoming IBM course z/VM Introduction and Concepts I have to agree. The class will start exactly a month from now and I currently have only three students. Apparently the same three students who were enrolled in its previous offering back in mid-November, which was cancelled due to low enrollment. This is a great ab-initio course for someone just getting started in VM and the public price is $1635 for the three days. I've been in the mainframe training business for twenty years and I assure you, it takes $2000-4000/day to put on a lecture/lab class of any quality with a subject matter expert for an instructor. It's not hard to do the math and see that Education in not one of IBM's major revenue centers...

As to affordability, I guess the question is whether the cost is in line with the benefit. What criteria do you have for affordability? And effectivity? At one point, I was going to make a ton of easy money cranking out self-paced learning courses. The deeper I got into it the more obvious it became that the only students who actually retained any information from the courses were the very ones who learned quite well from reading manuals in the first place. The material is obviously delivered towards the visual learner and the exercises have to be constrained to the limits of the course environment; there's no go play around and explore with self-paced courses. But mainly, there's no raising your hand and asking a question to clarify your (mis)understanding. No instructor with years of experience crafting analogies, real-world examples, or comparisons to concepts you already understand. (Until the cows come home, if necessary.) And no one to winch you out of the ditch when your playing around leaves you stuck in the weeds. With self-paced courses, you either get it from the text or you don't. Then there is the cruelest aspect of self-paced courseware, as exemplified by [EMAIL PROTECTED]: Would it make sense to have some kind of computer (okay, PC) based education - where the student (their company) buy the class, and the student could not only take the class on his own time - but could refer back to it when he/she shoot themselves in the feet?? On his own time? What own time? How many of us work an eight-hour day and go home to enjoy sixteen hours of our own time? Besides, how much technical material are you able to absorb after a more typical 10-12 hour workday? In short, there is no shortcut. By corollary, there's no cheap-cut either. If you want (to be) a well-trained staff member, it's going to cost some money and time. Preferably time away from the office and interruptions. Time away from phones and crackberries. Time to concentrate fully on the material being learned, and to practice the skills you came to acquire. IBM has a great VM curriculum (most of which I don't teach) including the outstanding Installing, Configuring, and Servicing z/VM for Linux Guests. This course is so popular the instructor's never home. But if you want my recommendation for a good SysProg jumpstart course, check it out. -Chip Davis- [EMAIL PROTECTED]

Re: Impromptu XEDIT Survey
On the right, of course.:-) That way, both the prefix area and the next line are both a single keystroke away. From anywhere on a line, a CR takes you to the beginning of the next line, a TAB takes you to the prefix area. And then there's the human-factors aspect of wasting valuable screen real estate on the left margin where the human eye expects to find text, only to have to skip over a PDF/EDIT-style prefix area. Not to mention the presentation change when the prefix area is turned off; if it's on the right, the only difference is you might see more of each line. The text in column 1 stays in column 1. I thought this issue was settled back in the 80's ... ;-) -Chip- On 2/20/08 15:04 Dave Jones said: On the left, of course.:-) Huegel, Thomas wrote: Where does the prefix field belong?

You mean you actually over-type what is already there on the screen rather than orchestrate changes through the command line and prefix area?:-) If that is what I want to do, yes. If I need a fresh line, it's only three keystrokes (tabaenter) one less than is necessary if the prefix is on the left (crupaenter). Add one more character to invoke SI. The main point is that with the prefix on the left there is no difference between a TAB and a CR; you're going to go to the prefix area whether you want to or not. With the prefix on the right, you have the choice of going to the prefix area with a TAB, or the beginning of the next data line with a CR. What good is having the choice if you don't take advantage of it? You would not if you learned XEDIT on a 300 bps terminal... that's how you learn the order in which prefix commands, screen updates and command are processed. And when someone managed to put a FULLREAD ON in some of our shared macros, you'd have enough time to hit him over the head before your screen refreshed ;-) Oh, but I would, Rob. And that's exactly where I learned the editor, only it was EDIT under VM/370 BSEPP. XEDIT came much later. But that's the beauty of the design of XEDIT: the user can choose the display and behavior of the tool that suits the task at hand. You can put the prefix in the _middle_ of the line if you want to ... A toast to Xavier de Lamberterie! -Chip-

The solution was actually pretty embarrassing. The solution was to vary the device offline/online to the correct z/OS system. I had recognized the need to vary the device offline/online before I even solicited input from the community. However, my backup job was redirected to a different z/OS system from the one where the varies occurred. So, there was no problem with the z/VM sysres volume which was built by the installation process. Probable user error. Thanks to all of you for your input.

The installation, while slow, has completed successfully and I'm able to IPL the newly-installed system. Thanks, IBM, for allowing me to bypass all those tapes. I don't yet have access to any tape drives under VM so I'm depending on z/OS to backup my newly-installed volumes, 530RES, 530PAG and 530SPL. However, I experience S213-04 abends (can't find SYS1.VTOC on the volume) attempting to backup these volumes using Innovation's FDR under z/OS. z/VM was shutdown and I varied the volumes offline/online to z/OS following the first failure, hoping that might correct the problem. I've used the same product/technique many times before in a past life and I know the process works. I suspect the installation process (whether its something inherent to v5.3 or something unique to the FTP server install process, I'm not sure) is not initializing these volumes with the dummy VTOC required by z/OS. I did not override the default volume format option of the installation. I suspect I need to run ICKDSF CPVOLUME FORMAT (or CPFMTXA FORMAT) against cyl 0 on each of these volumes (first documenting and resbuilding the allocation maps) and then run SALIPL to rewrite the Loader IPL text on 530RES. Be aware that I'll more than likely be doing this against a running system without a backup (I'll probably try to DDR MAINT 123/124/125 to another volume, for a small amount of insurance). I think that's what I need to do but I want to run it past the community because I don't want to go through that multi-day installation again. Does this sound reasonable?

Re: z/OS + TSO + ISPF versus z/VM + CMS + ISPF
This won't help Raymond any, but it reminded me of something. I used to write a lot of panel apps using a VM program product called Display Management System for CMS. It had interfaces for EXEC/EXEC2, COBOL, PL/I, RPG, and BAL, but I used REXX with no problems. Admittedly it was ISPF-Lite but it did everything we needed for some pretty sophisticated applications. It has a slick (well, for 1980) interactive panel design tool that would let you build anything a 327x could display.
