Re: [Emc-users] Conditional code- GOTO
Hi to all. Wondering why the GOTO feature is a bad thing to have I was reading a USA brand CNC manufacturer (Delta Tau PMAC-NC Pro2 http://www.deltatau.com/manuals/pdfs/PMAC-NC%20Pro2.pdf) and they use GOTO as a standard function for the NC program control into parametric programming FANUC style . And they declare : To maintain FANUC compatibility, this form of a conditional expression should be adhered to. GOTO expressions goto can be followed by an expression Regards Alex :-) On Tue, Oct 7, 2014 at 3:50 PM, Dave Cole linuxcncro...@gmail.com wrote: On 10/7/2014 9:05 AM, Mark Wendt wrote: On Tue, Oct 7, 2014 at 8:51 AM, Dave Cole linuxcncro...@gmail.com wrote: Ugh.

And every one of those ways is better done using if/else/endif or while/endwhile or do/while instead of goto. Thats an awful absolute statement! There are some cases where gotos are appropriate and FAR more clean then if/else/etc. I write code for a living and have one particular case that is a nightmare to solve w/o one. The LWIP stack uses them in a handful of places. Clean and non-offensive. I don't see why some are getting their panties in a wad over it. Chuckle, ya need 4WD to go over or around densely wadded dogma. Here is one of those cases you refer to, I think. The code is part of an event-handling state machine, written in my own dialect resembling SDL, and in this case is a snippet from a menu system which handles a 12-key keyboard and a 2 x 16 character LCD, running on an ATmega328p. (A hacked Arduino board) The plot so far: The event-drive OS delivers an incoming event to the current state, and at state INDEX, we handle a keystroke of 1 or 2, which are used as softkeys, aligning under the display's bottom line, currently showing By_Size By_N/rev, following a prior selection of Index at the higher menu level. It is worth remembering that in an SDL state machine, execution for an event is called a transition, and comprises one string of code, without subroutines. (In this case, the code is a bunch of assembler macros, so not particularly recognisable out of context.) The join IN1 is effectively a Goto, which makes 6 lines of code common to the two modes. That's how the SDL language handles transition merging. Admittedly, commercial tools do it graphically, with automated code generation, so the Goto is just a line on the page, which makes it immune to dogmatic attack. state INDEX if_event 1 ; By_Size (raw) mode. display indx_11 L1; indx_11 is Hops Size #=Ent IN1: vst mode event ; Save mode, and use INDEX_HOPS for both. display prompt_1 L2 ; *=bs (backspace) write_lcd control 0x0F; Set cursor blinking. place_cursor 0 L2 ; at start of line 2. send self First ; Make stuff happen there, before next_state INDEX_HOPS; any external events. if_event 2 ; By_N/rev mode. display indx_10 L1; Hops N/rev #=Ent delay 1000; LCD ignores next line if we're too quick. join IN1 state INDEX_HOPS; ACCU_DISP collects any keyed data entry, if_event First ; sends a Return event to the calling state. vst tmp zero_reg; Instance variable tmp = 0 call_state ACCU_DISP ... OK, it would have been possible to cook up a prettier artificial example, but this code is running on the little Arduino board on the corner of my desk at the moment, and I've just added the join while adding the new mode, so it'll have to do as an example. Dogmatists please note that it is 100% legit SDL to whiz off to merge into a transition tail at another state, and that is in fact its most common use in industry. Why use such a state-based code architecture? Each event is handled with extreme efficiency, delivered to the current state by the event-OS, handled in a few lines of code, i.e. in microseconds, often. (All those macros are in-line code, so no call/return overhead.) Each instance gets a couple of negligible-overhead timers, eliminating the need for spin delays, which cannot exist in a multi-threaded real-time environment. And if you've used this stuff to control a turret, toolchanger, or other gizmo, then later add a second one to the machine, it is only necessary to change define_sm turret TURRET_INIT 1 to define_sm turret TURRET_INIT 2 and a second instance comes into existence, sharing the code, but with private instance (thread) variables and instance ID. (Whoops, sorry, this was just supposed to be a code example.) Erik P.S. The macros for the action primitives are a moving feast, hopefully improving in elegance over time, but even now providing a useful level of abstraction over the raw assembler underneath. -- The surest way to corrupt a youth is to instruct him to hold in higher regard those who think alike than those who think differently. - Nietzsche -- Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?

About 10 miles of i-70 where i-79 uses it to make a job west, but the northbound side of that, which blew me away, that big 25 mph 290 degree right turn to get on i-70, the one with the 15 foot tall crash barrier on the outside? The corner that killed at least 10 people a year? Yeah, that one, not far from Washington PA. That has finally been replaced with a huge, 75 degree sweeper to the left you could do at 100 mph, standing on pylons about 75 feet tall over everything else. Sweet! But generally, PA's good roads haven't gained any speed increases, stuck at 65 mph by PA. Nobody pays much attention to it as traffic generally stays north of 70 mph, sometimes by another 15 mph. My Toy saw 80 trying to run with them 2 or 3 times. However PA is still building 3 to 4 year roads, cheap as heck, gotta keep all the union road workers off welfare I guess. I have seen potholes in i-79 develop before they get the gear packed up at the end of the job. If I was a PA taxpayer, I'd sue. 20% more per mile will build a 30 year road. How they do it is criminally fraudulent waste of tax dollars IMO. Seems I read someplace where if federal dollars are involved, its a package deal, and you cannot ask for a warranty.

Cheers, Gene Heskett It seems I have missed the plot... What makes you say that? This plot revolved around having two of my 4, or 5 if you count the 2nds only surviving child, boys here to help me celebrate my 80th, one of them had a hard time rounding up enough sheckles for the airplane tickets. He is the oldest, fresh out of rehab hitting every AA meeting he hears about yet. His first wife caught quick pneumonia passed 4 years back, hit him hard he crawled into a bottle, but he now has a new woman he signed up with about 2 years back, who is determined to dry him out and keep him that way. She seems nice except for a very quiet but non-stop mouth, which he needs I think to prop him up. I'd eventually stick a hot tater in her face for a muffler, but thats just me. :) My wife's COPD is progressing, and it takes air to talk, so we don't talk as much as I'd like. This fall weather has got her down but the last day or so we've had a bit of rain to clean the air, which seems to be helping a bit. So other than that, no real plot, just life, one day at a time. :) FWIW, on that post about the Atten scopes, it seems the are several Chinese makers using that std platform, even some US pedlars are using it, name brand stuff even. So while Atten's support isn't, Siglent's is, so I now have an updated firmware here and have been trying to locate a usb storage medium, key or disk, which I have 2 of each in this midden heap, but so far no keys, and the one 40Gb usb drive I had has apparently frozen up, won't spin up. I expect the scope wants to see a vfat file system, so it probably won't do me any good because I think I've formatted every key I own to ext3. But keys are cheap. I just found a 2Gb sandisk key, and by golly its mounted as a vfat! And it had plenty of room for those 2 files. Done. But I'm going to play a bit before I open that menu. acc the status display its firmware is prehistoric. 1.08, hdwe version 1.00. And it can't find the file on the key. I wonder if I have to rename it? I bookmarked a bunch of help sites last night, to to go re-read them. Results posted later. Might have to rename it, currently is named as an SDL# and its probably looking for an ADS#.

Re: [Emc-users] Conditional code- GOTO
I consider Hal to be a programming language of sorts.Its a setup language, but still a language. Mach3 required VB or Brains (an attempt at Ladder Logic) to do any modifications. I don't see how a complex machine can be setup without some type of configuration code/hal/ini configuration.

(which isn't that much but a whole lot more than zero...) If you go for the 'hobby' version of mach4 you don't get the fanuc style macroB language extensions. So as I under stand it - you are stuck with the mach3 style language that has no conditionals and such (ie - linuxcnc before owords - which is what Art started with). $200+ more if you want the printer port module - otherwise you need to buy external motion hardware. (which is usually more than mesa, pico or other linuxcnc supported hardware with less flexibility) I still get a kick out of 'needing to be a programmer' to use linuxcnc.. Mach4 is supposedly a lot more flexible to modify. Guess what you have to use - lua - a microsoft programming language.. Before that you had to use 'brains' which was some sort of vb like language..

But several of the board members are now obviously aware of your desire to have a GOTO instruction in the LinuxCNC gcode language. I honestly don't know how to do it . Ok.. I didn't know. I just wanted to try and help you. So you will need to convince someone else to alter the program and submit a patch for review. Then it may or may not be included in the official releases of LinuxCNC in the future. However, if you have a patch, you can apply that to LinuxCNC yourself and recompile the program and gain that functionality. There are instructions on the LinuxCNC website on how to get and compile the LinuxCNC source code. Never in my mind to see a so strong reaction from a part of the people I read . Don't take it personally. Some programmers have strong negative feelings about the GOTO instruction. Some really horrendous code has been written with the help of the GOTO instruction. Extensive use of the GOTO instruction is generally associated with bad programming practices. And I guess I am one of them crusty old programmers as I'm celebrating my 80th today. I have carved code in several languages but except for some early efforts in basic, haven't used a goto in any other language that effectively did have it by whatever name. I have, after that basic disaster, which was scrapped in the long run the function re-written in assembler and C combined, pretty much looked at a goto as the equ of a painter painting himself into a corner. Its not only embarrassing, but seems to show a lack of forethought in how to go about solving the problem at hand. That isn't intended to insult anyone who does use it by design, just that I have learned to think about how to do it which automatically assumes it does not exist, and usually have a pseudo code written out and printed as an outline to follow before a real line of code is typed. Can you kindly explain me how to express an official request to the LCNC board of developers. Making an official request to the board may very well result in no changes unless they personally are interested in making the changes. Here is the official How to contribute web page. http://www.linuxcnc.org/docs/html/code/Contributing-to-LinuxCNC.html First of all I'm not so comfortable with the english writing to express my self fully . You do very well. I'll have to agree. I tried during the thread to explain why the GOTO (or whatever function/instruction can do the same thing) can be useful to produce clear and well structured G code but maybe I failed . I don't think that was an argument that you or anyone else could win on this list. If a feature is transversal between different CNC manufacturers to be a sort of standard why LCNC shudn't have it ?

As Chris Radek wrote : If someone wants to, and it gets done in a sane way (I think the 0xxx LABEL ... 0xxx GOTO would be most consistent with the way our O words work), let's, as they say, thoughtfully consider the patch. can be a good starting point.

The program used a large variety of signal generation and signal processing modules to predict how designs and design changes would change performance.. The program generated simulated radar returns from simple and complex targets (things we might want to see), clutter (the things in the environment we didn't want to see) and jamming (signals the enemy might generate to make things difficult) for radar configurations, and dynamics. (What comes out of radar antennas is dependent on the relative dynamics of anything that might be reflecting radar energy as well as antenna design and pointing. ) There were modules to generate the various radar returns for various conditions and designs. There were also modules to model the various signal processing elements in radar receivers, etc. The program flow was controlled by an integer array telling it what to do next after if finished each step using a 200 branch go to statement. It required a good understanding of radar systems and signal processing to run this program. It was used to aid the design of a number of radar and sonar systems. Thirty years after I left that company somebody told me they just found a bug in the program. They were still using it. Craig
Re: [Emc-users] Conditional code- GOTO
Hi Alex, I never asked to anybody on the board this issue. I understand. But several of the board members are now obviously aware of your desire to have a GOTO instruction in the LinuxCNC gcode language. I honestly don't know how to do it . Ok.. I didn't know. I just wanted to try and help you. So you will need to convince someone else to alter the program and submit a patch for review. Then it may or may not be included in the official releases of LinuxCNC in the future. However, if you have a patch, you can apply that to LinuxCNC yourself and recompile the program and gain that functionality. There are instructions on the LinuxCNC website on how to get and compile the LinuxCNC source code. Never in my mind to see a so strong reaction from a part of the people I read . Don't take it personally. Some programmers have strong negative feelings about the GOTO instruction. Some really horrendous code has been written with the help of the GOTO instruction. Extensive use of the GOTO instruction is generally associated with bad programming practices. Can you kindly explain me how to express an official request to the LCNC board of developers. Making an official request to the board may very well result in no changes unless they personally are interested in making the changes.

Don't assume that there is a pool of programmers on call being given tasks by the board to add features on request. As for the feature being discussed, it looks like a fairly simple change to a single C++ file that I linked to earlier. There is no need to be a trained software engineer to experiment on that file with adding a GOTO statement. That was how I started when I decided to add support for the Mesa three phase PWM, just looking at existing code and adding modified versions, and learning C at the same time.

Re: [Emc-users] Conditional code- GOTO
You also forget to mention that to get the industrial version of mach4 you are going to pay $1000 -$2000. (which isn't that much but a whole lot more than zero...) If you go for the 'hobby' version of mach4 you don't get the fanuc style macroB language extensions. So as I under stand it - you are stuck with the mach3 style language that has no conditionals and such (ie - linuxcnc before owords - which is what Art started with). $200+ more if you want the printer port module - otherwise you need to buy external motion hardware. (which is usually more than mesa, pico or other linuxcnc supported hardware with less flexibility) I still get a kick out of 'needing to be a programmer' to use linuxcnc.. Mach4 is supposedly a lot more flexible to modify. Guess what you have to use - lua - a microsoft programming language.. Before that you had to use 'brains' which was some sort of vb like language.. I just don't understand.. I have setup many many machines without having to do any 'programming' with linuxcnc. Correct me if I am wrong..

Some corrections.

Re: [Emc-users] Conditional code- GOTO
That usage does NOT require a goto, a conventional if statement works: O100 if [#8 NE #0] #8 = #9 O100 endif If your goal is to either skip or execute some code based on a condition, a regular if/else/endif structure does the job, while still enforcing structured code and avoiding spaghetti. There are plenty of ways to use goto that are clean and structured. And every one of those ways is better done using if/else/endif or while/endwhile or do/while instead of goto. The things that can't be done with if/else/endif, while/endwhile, or do/while are typically the things that really shouldn't be done, and that lead to spaghetti code.

Re: [Emc-users] Conditional code- GOTO
That usage does NOT require a goto, a conventional if statement works: He was simply pointing out the syntax. Of course a two line statement didn't need a goto. There are plenty of ways to use goto that are clean and structured. And every one of those ways is better done using if/else/endif or while/endwhile or do/while instead of goto. Thats an awful absolute statement! There are some cases where gotos are appropriate and FAR more clean then if/else/etc. I write code for a living and have one particular case that is a nightmare to solve w/o one. The LWIP stack uses them in a handful of places. Clean and non-offensive. I don't see why some are getting their panties in a wad over it. If someone wants to write code using it (or has existing code) what difference does it make to others? LCNC is about having more flexibility and freedom not less. If you don't like the taste of coffee fine, go drink your tea. But don't ban or look down on coffee drinkers because you don't like it. They achieve the exact same end goal. As it has been pointed out, commercial controls support it and if someone has an existing program that CANT be run on LCNC thats a big problem to that user. I wouldn't want to have to hand unwind, learn, and rewrite some old code that worked perfectly before. -- Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?

LCNC is about having more flexibility and freedom Wow this is bringing out strong feelings. The sticking point here, which I don't think is reflected in your message, is that if we want Oxxx GOTO, someone would have to implement it. Nobody has stepped up who wants to do that. If someone wants to, and it gets done in a sane way (I think the 0xxx LABEL ... 0xxx GOTO would be most consistent with the way our O words work), let's, as they say, thoughtfully consider the patch. But until someone wants to implement GOTO, can we all stop yelling about it?

Re: [Emc-users] Conditional code- GOTO
The 200 branch go to: Many years ago,/in the days of punch cards and mainframes,/ I wrote, /in FORTRAN/ a complex radar system modeling/simulation tool to evaluate radar system designs in a variety of environments. The program used a large variety of signal generation and signal processing modules to predict how designs and design changes would change performance.. The program generated simulated radar returns from simple and complex targets (things we might want to see), clutter (the things in the environment we didn't want to see) and jamming (signals the enemy might generate to make things difficult) for radar configurations, and dynamics. (What comes out of radar antennas is dependent on the relative dynamics of anything that might be reflecting radar energy as well as antenna design and pointing. ) There were modules to generate the various radar returns for various conditions and designs. There were also modules to model the various signal processing elements in radar receivers, etc. The program flow was controlled by an integer array telling it what to do next after if finished each step using a 200 branch go to statement. It required a good understanding of radar systems and signal processing to run this program. It was used to aid the design of a number of radar and sonar systems. Thirty years after I left that company somebody told me they just found a bug in the program. They were still using it.
