Static Call - 1) Identified by CALL Literal i.e CALL 'PGM1'
USING... 2)Compiler option must be specified as 'NODYNAM'.
3)If the subprogram i.e PGM1 undergoes any change, the main
and sub modules need to be recompiled. 4)submodules needs
to be link edited to the main module. 5) Size of the load
module will be large.
Dynamin Call - 1) Identified by CALL literal with the
module being passed through a variable. i.e CALL WS-PGM1.
2) Compiler option must be specified as 'DYNAMIC'
or 'DYNAM'. 3)If the subprogram which is being called
dynamically undergoes a change , the subprogram is alone
compiled enough to take effect of the changes. Compilation
of main module is not necessary. 4) submodules are picked
up from the load library when the program runs. 5) Size of
the load module will be less.
