Thanks, that is my sticking point - can I avoid creating those prototypes?
You really, really, really shouldn't do that. I've spent days tracking down bugs from people who didn't bother because it "just worked" on their system.
Just make a simple .h file:
Code:
#ifndef __MYHFILE__
#define __MYHFILE__
extern int set_p(int p1, float p2, int p3, int p4);
#endif/*__MYFILE_H__*/
...and include it in both c files.

Also, why would this code run OK when compiled by the old SCO compiler?
Undefined behavior doesn't have to be the same everywhere. That's part of the problem.
I need to pass a parameter to a function in a script. My parameter is a string. When I display the parameter within my function, I only get the first word from string I pass in.

Hi All,
When passing parameters to a sheel script, the parameters are referenced by their positions such as $1 for first parameter, $2 for second parameter. these positional values can only have values ranging from $0-$9 (0,1,2,3...9).
