Starting the disassembly view

To start the disassembly view:
  1. Enter the SET DISASSEMBLY ON command
  2. Open the program that does not contain debug data. z/OS® Debugger then changes the language setting to Disassem and the Source window displays the assembler code.

If you enter a program that does contain debug data, the language setting does not change and the Source window does not display disassembly code.
