Can I use a C shell script for my PLC stuff?

I tried running comp on the code listed above and got the following feedback.Anybody know what it means????

root@jr1050-desktop:/usr/realtime-2.6.32-122-rtai/modules/emc2# comp --install buttonlogic.comp
Traceback (most recent call last):
File "/usr/bin/comp", line 1321, in <module>
main()
File "/usr/bin/comp", line 1290, in main
process(f, mode, outfile)
File "/usr/bin/comp", line 1164, in process
a, b = parse(filename)
File "/usr/bin/comp", line 404, in parse
a, b = f.split("\n;;\n", 1)
ValueError: need more than 1 value to unpack


they seem to be Python errors,comp appears to be written in python.....

Thank you for the quick response.I fixed the variable syntax and a few other snafu's(that were brought to my attention by the comp program.At one point I even cut the file down to the first function.This is my first go at full blown c progamming(Im used to fanuc macro and Delta Tau plc,which is like Basic and C combined).So for the dumb question,how do I run the pre processer?I didnt see any reference to it in the comp section of the manual.....Thanks again

The manual could use some fine tuning,it assumes you know the how the Comp program works and it is missing some key points of info like"to check for errors and preprocess your code,do this"!! I understand Emc is a work in progress and I do appreciate all the work the community puts in.After I figure this thing out,I would like to add to the missing info,you guys want some help?

Ok,Im at odds with this comp thing.I ran my code thru the preproceser and got the same same Value error as i posted before.I made a new file with the" constant" example from the manual and got this ;

oot@jr1050-desktop:/usr/realtime-2.6.32-122-rtai/modules/emc2# comp constant.comp
Traceback (most recent call last):
File "/usr/bin/comp", line 1321, in <module>

a, b = parse(filename)
File "/usr/bin/comp", line 404, in parse
a, b = f.split("\n;;\n", 1)
ValueError: need more than 1 value to unpack

The same thing.The only file I could get to rum thru comp is an example file for an orac tool changer.What simple thing am i missing?What is this value error thing and what is the meaning of line 404 and its associated code.This shouldnt be this hard....

GOT iT. I was trying to run this from the usr/bin ect directory.When I put it in the home folder with the other machine specific fiies and ran "sudo comp buttonlogic.comp",it ran.
DUHHHH
