Hi,

Initially compiler converts ur source language statements into Asembly language statements called object module and this is furthur converted to
machine instructions called as load module which is in the executable format.

Thanks

Hi,
In a Compiler-Link Jcl there will be one Compiling step which takes ur pgm frm the location and creates the object. It may be saved to a PDS or to a temporary file. This object is passed to the link step. And the link step creates the load module. There r cases where there may be two link steps. The first one creates the CSECT and the second one creates the load module. Only the load module is executable. The object may not even be saved if it is created in a temporary file.
