Instant Watch on $INCLUDE File CONST Name May Hang QB.EXE (42947)




This article was previously published under Q42947

SYMPTOMS

The QuickBasic environment may hang when attempting to add an Instant Watch on a CONST data name that is in an $INCLUDE file. Microsoft has confirmed this to be a problem in Microsoft QuickBasic Versions 4.00, 4.00b, and 4.50 and in the QB.EXE that is shipped with Microsoft Basic Compiler Versions 6.00 and 6.00b (buglist6.00, buglist6.00b). This problem was corrected in Microsoft Basic Professional Development System (PDS) Version 7.00 (fixlist7.00).

MORE INFORMATION

The two files involved are the following:

REM ---- TEST.BI -------
CONST TRUE = -1

REM ---- TEST.BAS ------
REM $INCLUDE: 'test.bi'

The following steps should cause the machine to hang. The steps must be followed closely to reproduce the problem:

  1. Load and run the TEST.BAS file.
  2. Choose the Include File command on the View pull-down menu.
  3. Highlight the "TRUE" CONSTant data name.
  4. Set an Instant Watch variable (press SHIFT+F9).
The machine is now hung and a reboot is required. If the same sequence of events is followed as described above with the following exception, then the machine will not hang:

In Step 2, choose Include File Lines instead of the Include File command.
