BUG: "Expression Evaluator Fault" Occurs with CHANGE Command

ID: Q103469

The information in this article applies to:

  • Microsoft FoxPro for MS-DOS, versions 2.0, 2.5, and 2.5a
  • Microsoft FoxPro for Windows, versions 2.5 and 2.5a


An "Expression Evaluator Fault" error message occurs when the WHILE clause of the CHANGE command is used.


Microsoft has confirmed this to be a problem in FoxPro for MS-DOS versions 2.0, 2.5, and 2.5a and FoxPro for Windows versions 2.5 and 2.5a. We are researching this problem and will post new information here as it becomes available.


The following code


will generate an "Expression Evaluator Fault" error message if the PAGE DOWN or PAGE UP keys are pressed. This error also occurs if you attempt to leave the record by pressing either the UP ARROW key while the cursor is on the first field or by pressing the DOWN ARROW or ENTER keys while the cursor is on the last field.
