Symbolic parameters are used to assign a value to a character string within the procedure.
Symbolic parameters are used for easy modification of the proc.
The user may assign a value to the symbolic parameter at the time the proc is invoked. So in the JCL you could mention what value needs to be picked by the proc where these symbolic parameters are used.
If no value is assigned to a symbolic parameter by the user, a default value is supplied by the proc.
