To Acquire a Work Area

To acquire a work area, code the UENTER/UEXIT macros as follows:

UENTER PRGNAME=name,
DATAREA=dname,
DATLEN=dlen
:
L R15,retcode
UEXIT
[Define work area here.]
dlen EQU * - dname

Important! You cannot code more than one UEXIT per program. If you need to exit from multiple code points, use branches to a single UEXIT macro.
