This is the request from our customer. they are planning to remove fileaid from our mainframe TSO sessions by this month release (july 12th). So they have asked us to analyze all JCLs which are present in the system. If the JCL has a fileaid step convert it to sort/icetool/filemanager. While doing this task one of the JCL had a DD01 COPY PADCHAR=X'00' for a variable length file. We are not able to find the relevant syntax in any other utilities. The fileaid step is the first step in the JCL and the input comes from some other system. Kindly help us..
