Should I use "SYSTEM" or "EXEC"

[moof15]

I am trying not to save this xml file in the program.
Should I use exec or system to first run the program?

exec"program.pl";

open(LOG, >"file-save.xml&quot || die " can't open the logfile to clear\n";
close(LOG);

Even though I can't quite figure out what your question is asking, I can tell you this:

exec() executes a system command and never returns.

system() executes a system command and returns when finished.

This probably is what you need to know in order to make your decision.
