IBM SC34-7012-01 manual An assembler program that calls Dfsms callable services

An assembler program that calls DFSMS callable services

*ASM XOPTS(CICS,NOEPILOG,SP)

*

*A program that can be run as a CICS transaction to Read and Set

*the BWO Indicators and BWO Recovery Point via DFSMS Callable

*Services (IGWABWO).

*

*Invoke the program via a CICS transaction as follows:

*Rxxx ’data_set_name’

*Sxxx 100 ’data_set_name’

*

*Where:

*Rxxx and Sxxx are the names of the transactions that will invoke

*this program. Specify Rxxx to read and Sxxx to set the BWO

*attributes.

*’data_set_name’ is the fully-qualified name of your data set

*100 is the value the BWO indicators will be set to.

*The BWO Recovery Point time will be set to the current date and

*time returned from the CICS ASKTIME function.
