This function can either drop all the valid REXX variable structures in the script, or drop only the
REXX variable structures with a specific stem name.
Parameters
ALL
Drops all the valid REXX variable structures (copy group structures, route list structures, path set
structures, Host-Discovered Array Index structures, and Host-Discovered Array structures) in the
script.
{GRP|PTH}
Drops the REXX variable structures with a specific stem name.
GRP
Drops the REXX variable structures related to copy group structures with a specific stem name.
PTH
Drops the REXX variable structures related to path set structures with a specific stem name.
stem-name
stem-name ~ <REXX prefix of 64 or fewer characters>
For either the GRP or the PTH parameter, specify the prefix of the copy group structure related to
the REXX variable structures to be dropped. If you specify the GRP parameter, the REXX variable
structures related to the copy group structures will be dropped. If you specify the PTH parameter,
the REXX variable structures related to the path set structures will be dropped.
Specifies the prefix of the copy group structure that contains information about the copy groups
whose REXX variable structures are to be dropped. This must be the same as the character string
that was specified in the STEM parameter of the YKLOAD command that was used to load the
target copy group. The specified stem name must end with a period.
Example
An example of the YKDROP command follows:
DO all_copygroups
@DROPRES = YKDROP("ALL");
CALL YKLOAD "GROUP(one_copygroup) ROUTE(routelist) PREFIX(BCMPRFX)
" STEM(MYCG.) MSG(MYMSG.) DAD(dadid)
ADDRESS TSO "YKQUERY STEM(MYCG.) MSG(MYMSG.)"
END
