Q66740: CTRL+NUM/ May be Read as CTRL+/ in DOS with NUM LOCK On |

Article: Q66740
Version(s): 1.00 1.10 | 1.00 1.10
Operating System: MS-DOS | OS/2
Flags: ENDUSER | buglist1.10

In versions 1.00 and 1.10 of Programmer's WorkBench (PWB), 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 the OS/2
DOS 3.x box, 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.
To reproduce this problem, assign a function or macro to CTRL+NUM/.
Then execute 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
Microsoft has confirmed this to be a problem in PWB version 1.00 and
1.10. We are researching this problem and will post new information
here as it becomes available.
