Function modules is like a small program (is not a suboutine because sub-routines are not standalone objects-i.e we cannot execute them alone) which are similar to 'functions' in C.

we can pass the varible and get the return values even with out knowing what is happening in its code.

they are standalone programs-i.e.we can debug and execute them alone unlike subroutines and macros and includes.
