DFHWOSM FUNC=TERM macro
The DFHWOSM FUNC=TERM macro terminates communication between the
overseer program and DFHWOS, and releases any associated storage. It must be
issued before the overseer program completes to ensure an orderly termination.
Input
The TOKEN value is the BUILD token.
Output
Register 15
Contains the following completion codes:
0 Communication terminated successfully
Nonzero
Request failed.
Customizing the sample XRF overseer program
The sample overseer program consists of four modules link-edited together. The
main module is DFH$AXRO; the other three modules are subroutines, described
below:
DFH$AGCB
sets up request parameter lists (RPLs), access method control blocks
(ACBs), and parameter lists.
DFH$ADSP
displays status information.
DFH$ARES
performs restart in place.
