Initialization Parameter Specification Processing

Parameters that are passed to a CA Common Address Space (CASRV) are processed as internal commands of the address space.

Note the following ways to pass internal commands to a CASRV:

A CASRV can be passed internal commands through the START CIB, provided the address space was created by a START command or a full-function start address space created by an ASCRE CREATE. For details about passing parameters through the START command, see the z/OS MVS System Commands publication. If multiple commands are passed in this way, they must be separated by a semicolon (;). These parameters can also be delineated by a forward slash, "/". Parameters that appear after "/" are passed to the hosted application.
A CASRV can be passed internal commands through the PARM= field on the EXEC statement image, provided the address space was created by a START command or batch job. If multiple commands are passed in this way, they must be separated by a semicolon (;). These parameters can also be delineated by a forward slash, "/". Parameters that appear after "/" are passed to the hosted application.
A CASRV can read parameters from a PARMLIB file using the READCMDS command. For details about passing parameters through the READCMDS command, see READCMDS.

A CASRV retrieves internal commands during the initialization of the Common Address Space Shell.

Examples

In both examples, the PARMS_FOR_MY_SERVER string is passed to the hosted application as-is.

Start Command

S IEESYSAS.MYADDRSP,,,(ATTACH%SERVER=MYSERVER,PGM=IEFBR14/PARMS_FOR_MY_SERVER),PROG=CASRVASI,SUB=MSTR,TIME=1440

PROC EXEC PARM=

//MYADDRSP EXEC PGM=&PROG.,
//    REGION=4M,
//    TIME=1440,
//    PARM=('ATTACH SERVER=MYSERVER,PGM=IEFBR14/PARMS_FOR_MY_SERVER')
