Submitted by: AdministratorBoth used to read sequentila file.
Read work file 1:
1. is a processing loop strating like:
Read work file 1 file1

end- work.
Here ---> file 1 is file name here and 1 is arbitary file
number which is translated into dataset names CMwk01 in jcl.
read work file once:
1. Reads only one reacord is to be read.
2. there is no processing loop
