Null Pointer May Cause VB for MS-DOS Run-Time Error R6001

PSS ID Number: 93016

Article Last Modified on 1/8/2003

The information in this article applies to:

  • Microsoft Visual Basic for MS-DOS 1.0

Attempting to compile a program that contains errors which cause many severe compile time errors, results in the BC.EXE compiler reporting an R6001 "Null pointer assignment" run-time error, and terminating immediately after reporting the severe errors.


Microsoft has confirmed this to be a bug in the Standard and Professional Editions of Microsoft Visual Basic for MS-DOS, version 1.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

Correcting the errors in the source code which are causing the compile time errors allows the BC.EXE compiler to compile the program normally.
