$ERROR compiler directive

The $ERROR directive generates a compilation error.

Format

$ERROR message

where

The $ERROR directive causes the QMBasic compiler to generate a compilation error. It is most likely to be used inside a $IFDEF conditional compilation structure to recognise that the program is in some way invalid.

Example

$IFNDEF PLATFORM

  $ERROR Platform not defined

$ENDIF

The above example generates a compilation error if the PLATFORM token has not been defined.
