Don't you believe in Conway's Law? Someone didn't understand and did it wrong (or at least incompatibly) and now it shall never be undone. The best we can hope for is that in the future we will have a choice between the two conventions, probably selected by a PARMLIB option.
In IBM's defense, they could point out that the length fullword is added by the access method on write and removed on read, so the programmer should never be aware of its content. Unless the programmer accesses the file directly with Unix Services. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
