Running one map from another on MVSBatch

[Mags1972]

I am calling one map from another map using Run command. While running it on MVS Batch, if i dont provide a DDName for the called map in JCL, i get an error saying no DDname found for the called map.

I want to dynamically decide which map is to be called and thats why i wont know the name of map being called while creating JCL. Is there any way to do this without providing the DDname??

If we use a PDS/E file for maps, we can specify the following in JCL:

//MAPLIB DD DSN=MAPLIB. PDS

And specify run maps as

RUN ("MAPLIB(MEMBER)", .....),

To call MAP "A" then "B"
RUN ("MAPLIB(A)",....)
RUN ("MAPLIB(B)",....)

So a change in JCL will not be needed with addition of new maps.
