Yeah.I finally know how to solve this problem. I edit my REXX to add a statement 'ISPFCL' and after logon I just press 'F3' to exit ISPF and then my REXX is got executed and it automatically invoke ISPF again.So my life woud be easier:)
When I'm working on another site,its logon procedure doesn't invoke ISPF directly.Instead,it just goes into line mode TSO and you should start ISPF manually.So my REXX on COMMAND filed of LOGON panel works properly.Anyway,at this time I've known the difference between these two sites which causes my question. Although I've no authority to modify longon procedure, I can still ease my work by this way.So I really appreciate your kind hints,Paul , Wayne and Marian ,thank you very much!
