Answer / shakila vinayagam

Before using GDG , We need to create GDG index and model.
IDCAMS (the 'AMS' stands for Access Method Services),
utility is used to create GDG index.
Once the index has been created, a model data set must
be created. This model data set contains specifications
for the DCB subparameters for all data sets that will
belong to that GDG. Programmer can override this default
values if he want.

2 Answers   IBM,


I have a Symbolic Parameter which can have a value say 01 or 02 etc. Now consider i have another Symbolic parameters which is used to get 3 digit code of months (JAN, FEB, etc) but for that i need to check the first symbolic parameter's value and provide its corresponding month's name in the second symbolic parameter. Say IF sym1 = 01 then sym2='Jan' ENDIF etc... In JCL, IF condition is used for RC, ABEND purposes of a step etc. When i use Symbolic parameter in IF clause it is showing Error message. Is there a way to get the above result possible in JCL. If you could provide me with an example, i would understand it better.
