Answer / pradeep kumar
Getmain is a named memory for the Linkage Section variables
in the CICS program. The variables are passed to the memory
using SET command. The SET command can be used only for 01
and 77 level group items.
Program will work even if GETMAIN is not coded, because the
memory will be allocated automatically by the compiler, but
if the programmer needs memory space for the Linkage
Section Variables explicitly, then he/she can use GETMAIN
to allocate memory and FREEMAIN is used to freeout the
allocated memory.
