In the QB.EXE environment in Microsoft QuickBASIC Version 4.50,
searching for and replacing a string does not work correctly if the
replacement string is longer than 39 characters. A longer replacement
string can be entered, but the editor truncates this string to 39
characters.

Microsoft has confirmed this to be a problem in QuickBASIC Version
4.50. We are researching this problem and will post new information
here as it becomes available.

This problem does not occur in the QBX.EXE editor provided with
Microsoft BASIC Professional Development System (PDS) Version 7.00.

QuickBASIC Versions 2.00 and 3.00 correctly make the substitution for
strings longer than 39 characters. QuickBASIC Versions 4.00 and 4.00b
do not allow a string longer than 39 characters to be entered as the
replacement string, so the problem doesn't occur in these versions.

To duplicate this problem, do the following:

1. Start a new program in QB.EXE from QuickBASIC 4.50 and enter the
   following line:

      PRINT

2. Choose the Search menu by pressing ALT+S, then press C.

3. Enter "PRINT" as the string to find and
   "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa1234567890" as the
   replacement string (39 a's, followed by numbers).

4. Choose Change All by pressing ALT+C.

The editor will replace PRINT with the given string, but it will
truncate the numbers off of the end.
