PostSubject: How to Copy all the Generations of a GDG   Thu Oct 11, 2012 8:30 am

this is helpful when you dont know how many generations there are(of course you can check 3.4 in the command line) but lets say you in a JCL you are creating you want to copy all the generation without the hassle of repeating the dd statement.

//step001 exec pgm=sort
//sortin dd dsn=<GDG base here>, disp=shr *may also be old or whatever you want
//sortout dd dsn=<your output dataset>,
// disp=(new,catlg,delete)
// lrecl=100,
// recfm=fb
//sysin dd *
sort fields=copy

What is a GDG base?

You probably have seen GDGs before. They look like the ones below.


by the way, GDG means Generation Data Groups

credit goes to the original uploader of the codes..
