I've dwell on some questions for days : 1,In TSO,I use 'listalc status' to find that SYS1.UADS has been allocated to DDNAME 'SYSUADS'. For a test, I issue 'allocate dsn(center.uads) dd(sysuads)' and get the meesage that filename is in use. I resort to manuals and know that to do this I must use 'REUSE' operand. However,I submit a job via JCL which also uses DDNAME 'SYSUADS' and there is no problem.
2,I have a simple cobol program who just opens a input file and closes it(select infile assign to infile). First I issue 'allocate dsn(md0006.input.qsam) dd(infile)' and succeed.Then I can use TSO command 'call' to execute the program successfully. However,when I execute the program via JCL without coding infile DDNAME,it fails. So I want to know the exact reason.My personal guess is that a job submitted by JCL is not executed in my TSO address space.Would someone be kind enough to give some explanation for me? Thanks a lot. -- Best Regards, Johnny Luo ---------------------------------------------------------------------- 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
