perl command line and file handle.

[Stephen]

Hello,
would the following work if the file name myprog.pl was replaced with
a filehandle or a reference to a filehandle?

system("perl myprog.pl ".$argvc);

this assumes you are using a tied buffer system
and have sent a list of commands into it

tie *FH, 'tiedbuff';
print FH "print \"Hello World\"\n";
print FH "print \"Goodbye World\"\n";
print FH "exit\;\n";

No.

Depending on the system, you -might- be able to use -f /dev/fd$N
where $N = fileno FILEHANDLE

If not, then you probably need to see perlipc
