Right Hand Pointer

M53, Invalid argument for font function

Introduced in the 1995 ANSI M[UMPS] Windowing Application Programmers' Interface.

Each of the functions $WFont, $WTFit and $WTWidth has a parameter that specifies the units in which some of the other parameters are expressed. The unit- specification parameter must be equal to either "PIXEL" or "POINT". If any other value is specified for the unit-speficication parameter, this error will occur.

In earlier printed versions of the 1995 ANSI M[UMPS] Windowing Application Programmers' Interface, this error was identified as M?8.
