The linkage conventions are documented in chapter 2 of the MVS Assembler Services Guide. You have not used the sample code provided in that manual. The samples use GETMAIN to obtain a new save area. The address of the new save area needs to be placed in Register 13 so that it can be used by any programs that you might call. Otherwise it is of no use. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
