Create member EX9 in library data set &SYSUID.JCL.CNTL, to contain the invoking Job Control for two executions of procedure GDGPROC.
The essential difference required is the Conditional Job Control should be used to ensure that the second step does not execute unless the first step is successful.
In this instance success means that the step issued a condition code of zero, and did not abnormally terminate.
This will require the use of IF and ENDIF statements.
