I need to run a program that need input at run time.
Is it possible to simulate this by perl?
Thanx

It depends.
You can open a pipe to the program and send the input through the pipe
(beware of buffering):
open(DST, '|', $program);
print DST "Input\n";

Or look at Perl/Expect.

For interactive use (where a line of input depends on something that
was output previously), a PTY-based solution (such as Expect.pm)
is the way to go.
