Re: [U2] Multiple OPEN statements
That school is very diverse and doesn't offer any standardization that seems to come up every once in a while on this forum. I appreciate the humor but I'm really trying to learn where people are taught their Pick/MV techniques (and defend them as gospel as they have been taught) as opposed to extending one language's disciplines to another, namely Pick/MV.

Re: [U2] Multiple OPEN statements
IMHO, my somewhat criticism of the OPEN THEN OPEN THEN as earlier
illustrated was focused on the standard opening of many files for the
program's purpose. 99.999% of the time the ELSE statement is meant to be
terminal, in that the program stops without further processing. That's why I
wrote an article in Spectrum a few years ago endorsing a technique I picked
up called OPENER as in CALL OPENER("FILENAME", FILEHANDLE) and the
subroutine handles the very repeated exception logic, ie informing the user,
returning to the menu etc. (P.S. my OPENER also prevents the opening of a
file to no handle, which is okay for tiny programs but not when you have 20
files and 19 have handles.)
The 0.001% of the other time there could be some programming need to be in
the ELSE part of the OPEN, as in your 2 examples or to create temp files on
the fly. But by and large OPEN is a forward moving process.

RE: [U2] Multiple OPEN statements
The CLOSE command has been used in UV and, if you're using UV/NET to access a file, you must close that file. Failure to do so will cause UV/NET to die when its file pool reaches its limit. I suspect not many sites ever used UV/NET so it's probably a rare piece of trivia and I offer it for what it's worth.

Re: [U2] Multiple OPEN statements
Probably a left over. Way back in early Microdata. You could only open one file at a time. There was no TO clause. You had the file opened. If you wanted to access another file, you had to close the current one and open the next. Kevin used Dartmouth as his base, so think pre-Micro$oft.

Re: [U2] Multiple OPEN statements
Call me old-school but I prefer top-down OPEN file TO handle ELSE STOP (sic) to get them all out of the way. Whether 1 or 50 files, the get all opened at the same time. If those choose to have a CALL OPEN.FILES internal sub or named commons, then that's also a respectable method. To have the main portion of the code be that indented only makes maintenance later that much more difficult. Very, very few people seem to label their END statements to indicate what they're matched to. Upon further investigation (using that programmers initials) i found that when there were 8 or more file, he did it in a more top-down or sequential fashion. That introduces 2 forms of coding for the same concept which is 1 form too many. That programmer is still at this client and uses the tired response "That's what I was taught" when shown how hard it is to follow all of those indents.

This style of programming was taught in classrooms all over the country before the advent of point and click programming.

Re: [U2] Multiple OPEN statements
Can't this whole concept be considered foolish as if there were 20-30 files (as many update programs have) then the programmer would have to use a different mental syntax.

Programmers grumbled. I said the source is in APP.PROGS. Change it if you prefer something different. No one did. Speaking of editors, I have an ED prestore macro that shows the level of indentation.

Re: [U2] Multiple OPEN statements
I call this structured programming gone wild. It's like "Girl's gone wild" only for programmers. Just wait until you have code that is indented 11 levels ... I'm not kidding. I am all for structured programming, and I'm willing to fight the GOTO demons until Armageddon but even *I* (yes even I) use the structure OPEN "CUST" TO F.CUST ELSE PRINT "Cannot open CUST file. Press any key ":; KEYIN(); STOP END It's one of the only times when I support multiple stop statements.

Re: [U2] Multiple OPEN statements
Mark, It strikes me as a very literal approach to coding. Early Pick didn't have OPEN...THEN, just OPEN...ELSE, and I know some people who experimented heavily with the THEN back then.

Well, that part I don't like, but shit happens I suppose. A bit like: OPEN FILE1 TO F.FILE1 ELSE GOTO 999 where 999 is a long way away. Personally, I'd code the above example as: OPEN FILE1 TO F.FILE1 THEN OPEN FILE2 TO F.FILE2 THEN OPEN FILE3 TO F.FILE3 THEN GOSUB PROCESS_STUFF END ELSE PRINT "CAN'T OPEN FILE3" END ELSE PRINT "CAN'T OPEN FILE2" END ELSE PRINT "CAN'T OPEN FILE1" STOP PROCESS_STUFF: EOF=0 LOOP READNEXT ID ELSE EOF=1 UNTIL EOF DO PROCESS, PROCESS, PROCESS REPEAT RETURN END or even as: GOSUB OPEN_FILES IF SHIT_HAPPENED ELSE GOSUB PROCESS_STUFF END STOP OPEN_FILES: SHIT_HAPPENED = "" OPEN FILE1 TO F.FILE1 THEN OPEN FILE2 TO F.FILE2 THEN OPEN FILE3 TO F.FILE3 ELSE SHIT_HAPPENED = FILE3 END END ELSE SHIT_HAPPENED = FILE2 END END ELSE SHIT_HAPPENED = FILE1 END IF SHIT_HAPPENED THEN PRINT "Can't open ":SHIT_HAPPENED END RETURN PROCESS_STUFF: EOF=0 LOOP READNEXT ID ELSE EOF=1 UNTIL EOF DO PROCESS, PROCESS, PROCESS REPEAT RETURN END > Now I know that Pick is pretty loose and forgiving.
