Well, that got terribly garbled. Trying a different way.

DOMTST CSECT
R2 EQU 2
USING *,R12
LA R2,CMD R2 POINTS TO THE COMMAND AREA
MGCRE MF=(E,LAREA),TEXT=(R2),CMDFLAG=(NOHCPY),CONSNAME=MYCON
CMD DS 0CL6 THE COMMAND AREA
CMDLEN DC XL2'4' LENGTH OF COMMAND
CMDCOMM DC CL4'D C ' THE ACTUAL COMMAND
MYCON DC CL8'CON4 ' NAME OF ISSUING CONSOLE
LAREA MGCRE MF=L LIST FORM OF MGCRE
END
It's inconsistent that there is an EQU for R2 but not R12.
The content of R12 is nowhere defined, by e.g. LR R12,R15.
Has this code been tested?
Outside this example, the doc does not mention a need for
CSECT addressability. Is this generally assumed,
or must it be asserted for each macro? |
