Units Some commands accept units of measurement. You can use a number of
different units: characters, centimeters, decipoints, inches, lines, millimeters,
picas, or points. You specify them as CHARS, CM , DECIPOINTS ,
INCHES, LINES, MM, PICAS, or POINTS (you can abbreviate any unit
name with its first two or more characters). Whatever unit you use,
TFORM stores it in the form of decipoints. Table 1-1 is a conversion list for
the various measurements.
Note that characters and lines are flexible units; TFORM converts them to
decipoints at command execution time, based on the current pitch setting.
