reset retained variables when switching concatenated files

Hello,

I have a process in mainframe that reads multiple files concatenated under the same ddname.

Is it possible to reset retained variables at the start of each file being read?

Thanks

Ubaldo

Yes. You'll likely need to modify your infile statement. The option EOV=variable

specifies a variable that SAS sets to 1 when the first record in a file in a series of concatenated files is read. The variable is set only after SAS encounters the next file. Like automatic variables, the EOV= variable is not written to the data set.

So you add EOV=NewFile (or similar to your INFILE statement);

If NewFile then do;

end;

I looked for it only into the z/OS companion manual....

Thanks you again
