I am making a system call with a huge sized argument. Here is the call: 
 !system ("perl", $perl_file, $comp, $warn_list_arg); or die "Program 
+exit";

[download]
where: $warn_list_arg at times contains about 8000+ strings, each string consisting about 60+ chars. This arg is delimited such that the invoked Perl process can unmarshall these args.

For a small sized $warn_list_arg, the call executes OK. For larger sizes such as 8000+ strings, it fails. Here are some specs:

Exit value: 255 ($! >> 8)
Signal num: 0 ($! & 127)
Core dump: 0 ($! & 128)

Is there a size limit on the buffer containing the args? How might I be able to pass such a big arg?

BTW: i resorted to this method of passing args since passing an array/list to the system call failed to pass the args on to the invoked process. Or is there some way to pass arrays in a system call?

Thnx for any suggestion/help.

Thanks to all u folks for yr replies: sleepingsquirrel nothingmuch davido eclark ccn Creating the process via a filehandle was the trick for me! BBK
