1. You did not establish addressability in the approved Assembler manner..
2. You did not set up the WTO parameters before issuing the macro.
3. You did not exit the program in the approved Assembler manner.

Many sites frown upon operator messages appearing on the console unless there is a good application reason for doing so. Are you sure your site approves of you doing this?

To robert sample,

yes,maybe i have no access to do this.I will contact my leader about that.thanks a lot.

What does access have to do with it?

Assembler programs require you to set up addressability via a USING statement to set the base register before you start referencing memory locations. If you do not do this, memory addresses cannot be fixed within the load module.

For consistency, you should set up the save area trace as well, using the standard linking of save areas in case a dump needs to be processed. You also need to load register 14 from your save area and branch to it to exit the program, so you return to the calling program (which established register 14 as the return address when calling your program). This has to be done before the LTORG because otherwise your data will be interpreted as machine code, with unpredictable results.

If you do not know how to do these things, you need to learn the basics of assembler from a coworker, team leader, or book before attempting to write code. Assembler, unlike higher level languages, severely punishes deviations from the standards by generating abends that are difficult to resolve.
