look intot these operators/functions and decide which is best for your purposes:
system - runs a program but doesn't return program output to the perl script. Returns exit status, if any, of run program instead.
exec - runs a program but exits the perl program as soon as it's called
`` (backtiks) - runs a program and returns program output back to the perl script
qx// - same as backtiks

whatabout pipes?
you should be able to read back live/streaming status if the program sends it... and you can definately send a bulk stream of data to the program; if the program wants to receive it.
EDIT/PS:
be careful you don't do:
unless you're not concerned about losing the exe =P
open my($what), "| bin/what.exe -p whatever"; close ($what);
EDIT/PS:
be careful you don't do:
open my($what), "> bin/what.exe -p whatever"; close ($what);

If it only works in Internet Explorer; it doesn't work.
