Sun Pascal: Pascal calls C
#2

	I am calling a C routines from a Pascal program to (among other things)
change directories.  I am using several other C routines to do other system 
calls and only the ones that get arguments (such as cstr) passed to them fail.
What is wrong with:

------------------------system_cd.c-------------------

#include <stdio.h>

system_cd (cstr)

	char *cstr;

	{
	char cmnd[50];
	sprintf(cmnd,"cd %s",cstr);
	printf(cmnd);
	system(cmnd);

	}
---------------------------------------------------------

it's declared in the pascal part like:

procedure system_cd (cstr: string); external c;

and called like:  {s is a string}

system_cd(substr(s, 4, length(trim(s))));

Simple calls like "system_pwd() { system("pwd") }" work perfectly.
