hi sandeep,
thanks for u r answer.
again i have the dought. in static call, both the will compiled together.
so there is no need to compile the main program. where as in dynamic call both will seperatly compiled. so there is necessary to recompile the main program.
plz clarify
regards
amar

In static linking, the called subroutine is link-edited into the calling program , while in dynamic linking, the subroutine & the main program will exist as separate load modules

Just to emphasize Anu's point, you DON'T recompile, you reLINK the subpgm.
