I have a program with a single input and single output file. The input file that i want to read can be any size (upto 1000 characters).
I want to read from this file and write to output file.
The problem i am encountering is
1. how do i find the size of the input data set (to match record length).
2. how do i ensure the size of the output data set is the same as input data set. How can this be specified in the JCL.
