Starting the APPC/MVS transaction scheduler address space

 
S ASCH,SUB=MSTR[,ASCH=(nn[,nn]...[,L])]
 

The parameters are:

ASCH,SUB=MSTR

Invokes the ASCH procedure and creates the ASCH address space.

ASCH=

Indicates which ASCHPMxx parmlib members APPC/MVS is to use. The default member is ASCHPM00. If you specify only one parmlib member, you do not need to enter the parentheses.

The ASCHPMxx members can reside in SYS1.PARMLIB or any other parmlib data set that is specified on an //IEFPARM DD statement in the master scheduler JCL. However, APPC/MVS cannot process data sets specified in the master scheduler JCL until the operator enters a SET ASCH command. For information about how to specify configuration information in a parmlib data set other than SYS1.PARMLIB, see the description of starting APPC and ASCH in z/OS MVS Planning: APPC/MVS Management.

The system will display the parmlib statements on the operator's console as it processes them.
