Symbolic variables are variables that are included within the model JCL for which specific values are substituted. These variables let the JCL and product control statements for a model JCL member be used over and over again, and let you add conditional testing, change data set names, use different calculations than the defaults, and so on.
There are two types of symbolic parameters:
- Automatic symbolics are replaced automatically when the utility is executed.
- User-defined symbolics require the entry of a value. The specified value replaces the symbolic when the utility is executed.
