Along those lines, here is another wild guess. When the system passes control to a program, such as by ATTACH, register 13 points to a 144-byte save area. It is possible that ICKDSF is now using more than 72 bytes to save its caller's registers. If so, and if the caller is only providing a 72-byte save area, something will be overlaid. The appendix on calling ICKDSF from an application program may have useful information. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
