SYMPTOMS

The following error may appear after you use a question mark to display the value returned from the VARTYPE() function:

Data type mismatch.

The question mark does not support the value returned by the VARTYPE() function when evaluating a variable created by the SAVE SCREEN command.

Use a temporary variable to store the result of the VARTYPE() function. For example:

   SAVE SCREEN to screenvar
   temp=VARTYPE(screenvar)
   ? temp

This behavior is by design.

Type the following commands in the Command window:

   ? "Hello World"
   SAVE SCREEN to screenvar
   ? VARTYPE(screenvar)

RESULTS: The error occurs.
