Why do you want to chain programs? This is a technique used by BASIC and COBOL
programs many many years ago to get over the problem that some programs were too
big to fit into memory so they were broken up into stages and the stages were
chained together.

Modern computers have lots of memory so this is very rarely an issue today.

Why not just write 'p2' as an include file and call it from within 'p1'?
