SYMPTOMS
The error message "File Does Not Exist" occurs on the READ command in a program after a VALID function is executed. This error may also occur in a format file after a VALID function is executed. In releases of FoxBASE+/Mac before June 1992, the error that results may be

Syntax Error

instead of

File Does Not Exist.



CAUSE
When a user-defined function (UDF) is called from the VALID clause of a GET, the UDF must return a value; otherwise, the error

File Does Not Exist

or

Syntax Error

will occur.



RESOLUTION
To eliminate the error in the sample below, change the last line of MYVAL.PRG from RETURN to RETURN .T..



Steps to Reproduce Problem
  Create a program called VALTEST.PRG as follows: USE :foxbase:tutorial:faculty.dbf

CLEAR @ PIXELS 15,13 GET faculty->last VALID myval SIZE 15,72 @ PIXELS 36,13 GET faculty->first SIZE 15,72 READ   Create another program called MYVAL.PRG as follows: WAIT "In faculty->last VALID function..press any key to continue" RETURN  In the Command window, type do valtest . When the GET fields appear, press the TAB key to move to the second field and execute the VALID function. A WAIT message will appear; press any key to continue, as directed.

The

File Does Not Exist

error will then occur and the highlighted line in the program is the READ command.
