Set or display Dump Formatter and Kernel Debugger disassembley and register options.

Syntax:

─┬── Y? ──────────────────────────────────────────────────────
   │
   │         ┌──────────────────────┐
   │         │                      │

               ├─── REGTERSE  ───┤
               └─── DISLWR    ───┘

Parameters:

• Default)
  Display current option settings.
  ?
  Display help for the Y command.
  386ENV
  Force the Kernel Debugger and Dump Formatter to toggle the environment setting between 286 and 386 modes.

  This affects the way in which commands interpret the register set. For example, in 286 mode, general registers are assumed, by default to be 16-bit registers. Under rare circumstances it necessary to force a particular mode to obtain a correct disassembly listing from the U command. Mostly this occurs in system code that is multi-modal and has juxtaposed sections of 32-bit and 16-bit code.

  The initial setting is 386 mode under OS/2 V2.0 and above.

  REGTERSE
  This has the same effect as the RT command.

  The initial setting is for terse register display.

  DISLWR
  This option toggles upper and lower case display of assembler mnemonics from the U command.

  The initial setting is for lower case mnemonics.

  Results & Notes:

  No information is displayed when setting options.

  When querying options those in effect are displayed, for example:

  -------------------------------------------------------------------------------##y
  386env dislwr regterse
  -------------------------------------------------------------------------------
  

  This shows that 386 environment is assumed, lower case disassembly is in effect and terse register display is active. If any one of these setting is toggled then the corresponding flag is not displayed.
