But, unless you have coded a 'bad' blocksize, you don't have to change your code, and you optimise your job without changing anything in the programme. Now, we could get pedantic about whether JCL is user code, but you write it and the system reacts. - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
