Causes generation of a CSECT statement and initialization code
for the format module named by the statement label. (If CODE=ENTRY
is coded, this statement must contain a label.) CODE=ENTRY is valid
only once per module.
EXIT
Generates the code to exit the module and also generates the
local abend work area used by the module.
EXITONLY
Generates the code to exit the module (the local abend work
area is not generated)
WORKAREA
Generate the local abend work area only
If the CODE parameter is omitted, a CSECT statement is
generated using the statement label coded on the previous CODE=ENTRY
form.
