Hi James,
> Thanks for ur reply. > But I get a compilation error which states- > 18 STIMER WAIT,BINTVL=VACATION > ASMA141E Bad character in operation code - WAIT,BINTVL=VACATION First, what level of HLASM are you running? Or the operating system release? Second, have you reviewed the Assembler Services Reference book: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/iea1a741/CCONTENT S I would also like to see the snippets of the generated code for the STIMER instruction and your BINTVL=VACATION instruction. That way we could see what was actually generated by your system. Provide the output a couple of lines before and after the area of interest. Hope this helps, Lizette Koehler ---------------------------------------------------------------------- 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
