I have a sequential file. I want to repalce char. appearing at 5th, 20th & 30th position by 'N', 'Y', 'A'. I DONT want to do this by writing COBOL Pgm. want to do by JCL only. Please suggest how to go for it.
The simple solution it is change command,but I don't know very many questions:
How this file is big ?
Is it FB or VB file ?
Depend on above we can use ISPF EDITOR or CLIST or IEBUPDATE program.
