Q66740: BUG: CTRL+NUM/ May Be Read as CTRL+/ in MS-DOS with NUM LOCK On

The information in this article applies to:

- Microsoft Programmer's Workbench for MS-DOS, versions 1.0, 1.1 
- Microsoft Programmer's Workbench for OS/2, versions 1.0, 1.1 
-------------------------------------------------------------------------------

SYMPTOMS
========

In the Programmer's WorkBench (PWB) versions 1.0 and 1.1, the CTRL+NUM/ (CTRL+/
on the numeric keypad) and ALT+NUM/ (ALT+/ on the numeric keypad) combinations
may be interpreted as CTRL+/ and ALT+/ (on the main keyboard). This problem
happens only in DOS or in the DOS 3.x box of OS/2, and only on certain
computers. This behavior will cause any macro or function assigned to CTRL+NUM/
or ALT+NUM/ to not execute when NUM LOCK is on.

STATUS
======

Microsoft has confirmed this to be a problem in PWB version 1.0 and 1.1. We are
researching this problem and will post new information here as it becomes
available.

MORE INFORMATION
================

To reproduce this problem, assign a function or macro to CTRL+NUM/. Then run the
TELL function (CTRL+T by default) and press CTRL+NUM/. The TELL function prompts
for a keystroke, then displays the name of the keystroke and the function
assigned to it. With NUM LOCK on, TELL will return the following:

  unassigned:Ctrl+/

With NUM LOCK off, TELL will return the following:

  <function name>:Ctrl+num/

This behavior is identical for the ALT+NUM/ key name, but works properly for all
other key names on the numeric keypad.

If NUM LOCK is off, or if the protected-mode version of PWB is run, this behavior
does not occur.

This behavior has been observed on the following machines:

  Northgate 386-33
  PS/2 Model 70
  PS/2 Model 80-311
