Need Help!- variable program

[caddisfly]

I recently was asked to create a variable program for are old fadal vmc4020.
It has an 88hs fadal control and is using format2.
In the program the operator has to set a couple variable such as the size of the stock and finish size needed.
The stock is a plate that is mounted to an indexer and the tools move to fixed position and mill the plate diameter to the disired diameter as the plate rotates.
The plates are very large and otherwise wouldnt be able to be machined on the this machine.
I haven't dealt with this machine in atleast 10 years and have written a number of variable programs for this machine back then with no problems.
The problem I have now is I am getting an illegal address alarm when the operator starts up the program.

Any help would be appreciated on what could be the problem with the syntext or format that could be causing the program to fail. Im sure its a simple issue that I just am not seeing.

I dont know much about sub routines variable calls, but it is calling L101 instead of L100 looks like to me..

L101 (READ VARIABLES)

[fizzissist]

I haven't done macros in Format 2, so this is new to me....but I don't see a clear register command at the beginning, and the parenthesis within the macro line could be the problem? In Format 1 a comment should follow an apostrophe.....

A comment should be (example):
N16#V11=SQR((V8*V8)-(V10*V10)) ‘Y CENTER OF BLEND

It'd help if you could post a program that works for you.

I'll try to confirm that with the manual when I get in to work but I agree, the control is expecting a math operation of some kind if you use ( ) with #

I stared at that a long time without spotting that. Good eye.

FF

L101 calls sub L100 1 time. L102 would execute it 2 times.

SBC Cycle, fizzissist,

That could be. I am looking at some old programs that worked years back and I'm not finding any comments using () on lines with #.

I will have to make the changes and give it a try.

You are on the money.

18.2.5 COMMENTS Comments are very important part of Macro programming. They explain the program to others, and remind the programmer why they wrote it the way they did. Comments on a macro line begin with an apostrophe ( ‘ ), and can extend to a total line length of 63 characters. N3 # V100=1.2345 ‘V100 IS THE LENGTH OF THE PART 2

I didn't know about the apostrophe thing. That's good to know, thank you.

Let us know what you come up with. This is a great post! I didn't see anything wrong first time through either. I haven't done any variables since I bought my CADCAM. A good refresher problem!!

Mastercam doesn't do O-ring grooves the way I like 'em, and Fadal doesn't have a canned cycle for them...so I wrote a macro that does 'em the way I like..(well, almost..I'll refine it as I have time)

Comments are the only thing that save my butt. Even as often as I use my own program, I still need to be reminded of what something does...and if I want to edit later it's invaluable.

[caddisfly]

After reading the posts ,I started digging around for the programming manual and found the same comment rule ( ' ) on the macro lines.
Makes sense that ( ) would not work on a macro line.

I'm confident enough it will work now. I'll find out later today.


Thanks again,

OOOPPPPS, fat finger syndrome!

Caddisfly--
The main issue I see with out running the program is that the comments must be separated by an apostrophe and not an open paren. The Parens are mathmatical operators in the Quick Basic computer language.
Remove the open and close paren and in put the apostrophes where needed and then try running the program to find any further possible bugs. Let me know if I can help.
