PRB: Letters A through J and M Invalid Object Variable Names

Last reviewed: April 16, 1997
Article ID: Q166936
The information in this article applies to:
  • Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 5.0a
  • Microsoft Visual FoxPro for Macintosh, version 3.0b

SYMPTOMS

The following error occurs when trying to access the properties of an object that is named by a single character from A through J, or M:

   Variable '<variablename>' not found.

CAUSE

The letters A through J are reserved by Visual FoxPro to reference workspace names. The letter M is reserved for backward compatibility with the SCATTER and GATHER commands.

RESOLUTION

Do not name object variables by the single characters from A through J or M.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

  1. Create a form.

  2. Place a command button on the form.

  3. In the Click event of the command button, place the following code:

          C=THISFORM
          WAIT WINDOW C.NAME
    

    When this code is run, it produces this error:

          Variable 'NAME' Not Found
    

If you need to use one of these letters as an object variable, use the following method to return the value of a property. This does not allow the setting of properties, nor does it expose any methods of the object.

      C="THISFORM"
      WAIT WINDOW EVALUATE(C+".NAME")
