To include this LOOP WARNING code, set the variable &LOOPWARN to ‘1’ and
reassemble the sample.
Assembling and link-editing the overseer program
The non-specific job control statements required to assemble and link-edit the
overseer program are the same as those required for user-replaceable programs,
and are described in “Assembling and link-editing user-replaceable programs” on
page 402.
The specific link-edit statements that you require are:
ORDER DFH$AXRO this CSECT is in USERTEXT(DFH$AXRO)
ORDER DFH$AGCB this CSECT is in DLOADLIB(DFH$AGCB)
ORDER DFH$ARES this CSECT is in DLOADLIB(DFH$ARES)
ORDER DFH$ADSP this CSECT is in DLOADLIB(DFH$ADSP)
INCLUDE USERTEXT(DFH$AXRO)
INCLUDE DLOADLIB(DFH$ADSP)
INCLUDE DLOADLIB(DFH$AGCB)
INCLUDE DLOADLIB(DFH$ARES)
ENTRY DFHXRONA
NAME DFH$AXRO(R)
If you change the overseer code in any way, note that the libraries
SYS1.SDFHMAC and SYS1.AMODGEN are required for the assembly, and that the
link-edit job step requires the entry name DFHXRONA. If you change any of the
DSECTs used by the sample overseer program, you should reassemble the four
modules.
