Return type: DECIMAL

Syntax

GET-TEXT-HEIGHT-CHARS ( [ font ] )

font

An integer expression that specifies an entry within the font.

If you pass the Unknown value (?) to this method, Progress uses the system default font. When a field-level widget inherits its font from the parent frame, Progress returns the Unknown value (?) for the font and you must use the font of the parent frame.
