The JCL procedures VIDASM, VIDDDMG, VIDDIMG, VIDDDLJ, VIDLBR, VIDDB2 and VIDSTGII in my.SVIDCNFG.custom are used by CICS® VT batch utilities. Either copy them to a JES procedure library, or use PROCLIB or JCLLIB statements to reference them.
The SYS1.MODGEN macro library data set name is hard-coded in members VIDGDMEX and VIDASM in the my.SVIDCNFG.custom library. If this data set has the name SYS1.AMODGEN in your installation, manually update members VIDGDMEX and VIDASM.
