PRB: "Missing Operand" Using TIME() with WAIT WINDOW Command

 Last reviewed: January 10, 1997
Article ID: Q156240
The information in this article applies to:
  • Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0

SYMPTOMS

In Visual FoxPro, you can use the WAIT WINDOW command with any character expression to display a message in the upper right corner of the Visual FoxPro desktop. However, when you try to use the TIME() function with the WAIT WINDOW command, as in WAIT WINDOW TIME(), you receive the following error message: 

   Missing Operand

CAUSE

Although the TIME() function is returning a character string, the WAIT WINDOW command is interpreting the first four characters of the function (TIME) as an abbreviation for the TIMEOUT command. The TIMEOUT command is expecting a numeric value as its first clause, but instead it is being passed a value of "()." Since this is not a valid numeric value, the "Missing Operand" error occurs.

WORKAROUND

You can use the following workaround: 

   WAIT WINDOW ""+TIME()  && Includes the double quotation

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

Type the following in the Command window: 

   WAIT WINDOW Time()
