hi, im a beginner in perl and am having trouble with system calls. I have a C program that runs properly when I call it using a terminal. It generates the files that it is supposed to generate. However, when I call this C program from a Perl program using system, the files that it is supposed to produce does not become created at all. I have already set the permissions properly (with chmod 777) but still, the files are not produced. What could be wrong? Thanks a lot...:)
