Specifying a window

HLASM Toolkit Feature Interactive Debug Facility User's Guide
GC26-8709-07

Many commands affect what is displayed in a particular window. There can be more than one Disassembly window, Dump window, or LSM Information window, open at once. IDF needs to be told which one is the target of commands like DISASM, DUMP, FOLLOW, LANGUAGE, SEARCH, and SET ALET. Similarly, with the CLOSE, MOVE, NEXT, PREVIOUS, and SIZE commands IDF needs to be told which window to use.

To tell IDF which window to use, you can use a Window Specification in the appropriate command. The Window Specification is an equal sign followed by the window's window number, in the form "=n". The Window Specification, if present, must precede any operands of the command. For example:
   DISASM =2 address
   FOLLOW =3 R9

You can also indicate the window IDF should use by placing the cursor in the window. As the cursor can also specify the argument of a command, a Window Specification, if present, is used in preference to the position of the cursor to specify the window to be used.

If you neither use a Window Specification nor place the cursor in a window of the appropriate type (Disassembly window for DISASM command, and so on), then:
  1. The DISASM and LANGUAGE commands use the first open Disassembly window.
  2. The DUMP and FOLLOW commands use the first open Dump window.
  3. The ARRAY, STRUCTURE, and VARIABLE commands use the first open LSM Information window.
  4. The NEXT and PREVIOUS commands scroll all the open windows.
  5. The SIZE and MOVE commands need the window type as an extra argument.
  6. The SEARCH command starts searching from the start address of the first open Disassembly window or Dump window.
