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.
