Need to read all generations of a mainframe GDG file

Hi,

I have a mainframe GDG file with about 50 generations and I need to read all of those through SAS on Unix.

Could you please tell me of a way through which I may just need to mention the infile statement once for the GDG base and it may read all of the generations of the g of that GDG.

-Thanks

Not sure I understand the question.  Doesn't the JCL take care of what generation it reads.  Do you want exact 50 or all generations.

Does this thread help?

Hi Tom,

Thanks for your prompt response... The files I want to read are on mainframes(all generations of a GDG) but my SAS process and jobs are in UNIX environment through which I need to read all these files hence I can not do it through JCL.

It's been a few years since I last touched a mainframe but you can use the SAS FILENAME statement to allocate GDGs just like JCL:

filename GDG 'name1.gdg' disp = shr; or filename GDG 'name1.gdg(0)' disp = shr; if you just want a single generation.

Create macro loop from 1 to 50 like

%macro loop ;

%do i=1 %to 50;

libname X1&i. " GDG name (&I.)" disp=shr;

data test;

   set X1&i;

run;

so on..
