SYMPTOMS
Running the CLEAR ALL command in the Command window results in an error such as:

Use of Unallocated Handle

-or-

This program has performed an illegal operation and will be shut down.



CAUSE
It is likely that you have used the STORE command to assign values to an array.



WORKAROUND
Instead of using the STORE command to assign values to your array, use the assignment operator (=).



STATUS
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was corrected in Visual FoxPro version 3.0b for Windows.



Steps to Reproduce Problem
  Run the following code: -=-=-=-=-=-=-=-=-=-=-=-=       BEGIN CODE -=-=-=-=-=-=-=-=-=-=-=-=  PUBLIC yy   yy = CREATEOBJECT("cc") RETURN

DEFINE CLASS cc AS Custom DIMENSION ee(1) DIMENSION bb(1)

PROCEDURE Whatever LOCAL ltemp

DO FORM C:\VFP\TEST NAME ltemp LINKED

*-- Use the following two lines to demonstrate the error. STORE ltemp TO THIS.bb(1) STORE ltemp TO THIS.ee(1)

*-- Use the following two lines to demonstrate the workaround. * THIS.bb(1) = ltemp * THIS.ee(1) = ltemp

ENDPROC ENDDEFINE -=-=-=-=-=-=-=-=-=-=-=-=    END CODE -=-=-=-=-=-=-=-=-=-=-=-=                         In the Command window, enter the following line of code: yy.Whatever   In the Command window, enter the following line of code: CLEAR ALL 

To work around the problem, change the STORE lines into comments and change the lines that use the assignment operator into executed lines to see the workaround.
