In the QB.EXE environment of QuickBASIC Version 4.00, 4.00b, or 4.50,
Microsoft BASIC Compiler Version 6.00 or 6.00b, or in the QBX.EXE
environment of Microsoft BASIC PDS Version 7.00, saving a module in
which a SUB or FUNCTION statement contains a syntactically incorrect
parameter list may cause QuickBASIC to fail to reload the same program
into separate windows. A SUBprogram or FUNCTION that was initially
displayed in its own window is now displayed (incorrectly) in the
window containing the module-level code.

If the error in the SUB or FUNCTION parameter list is now corrected,
and the cursor is moved to another line of code (using an ARROW key,
the ENTER key, or a mouse), the SUB or FUNCTION statement is correctly
displayed in its own window. However, any code that was contained
within the SUBprogram or FUNCTION remains with the module-level code,
including a copy of the END SUB or END FUNCTION statement. That code
must be manually moved (using Cut and Paste) from the module-level
code to the SUBprogram or FUNCTION.

To prevent this problem, always correct any problems that have been
noted by the QB.EXE or QBX.EXE environment BEFORE saving the file to
disk.

This information applies to the QB.EXE environment that comes with
QuickBASIC Versions 4.00, 4.00b, and 4.50 and Microsoft BASIC Compiler
Versions 6.00 and 6.00b for MS-DOS, and to the QBX.EXE environment
that comes with Microsoft BASIC PDS Version 7.00 for MS-DOS. This
behavior is a design limitation of these environments.
