ERR: "Operator/Operand Type Mismatch" with Logical Fields
Last reviewed: October 28, 1994
Article ID: Q100553
The information in this article applies to:
  • Microsoft FoxBASE+ for the Macintosh, versions 2.0 and 2.01

SYMPTOMS

Comparing a logical field with .T. or .F. and using comparative operators yields a "Operator/Operand type mismatch" error message.

CAUSE

This error is generated when you are trying to make a comparison on a field using the wrong type of operator, for example, trying to multiply a text string and a number together.

This error may also occur when you use a comparative operator on a logical field. A logical field in itself is a comparative operator and needs no other operator.

MORE INFORMATION

Examples

   REPORT FORM myreport FOR mylogicfield = .T.  && This will cause error
   REPORT FORM myreport FOR mylogicfield        && This is correct

   REPORT FORM myreport FOR mylogicfield = .F.  && This will cause error
   REPORT FORM myreport FOR mylogicfield        && This is correct
