Purpose Modifies the height and width for all designated fonts as set by the GSS
sequence.
Discussion Pn1 is a decimal value that specifies the height of the font as a
percentage of the height set by the GSS sequence. Pn2 is a decimal
value that specifies the width as a percentage of the width set by the GSS
sequence. Data processing fonts can be modified by two or three times
their default height.
GSM affects only the current print or plot mode. In Print mode, GSM always
changes the current pitch according to the newly selected font. In Plot mode,
the pitch is changed only if Pitch Select mode is set.
The GSM sequence is effective until the printer receives another GSM or
GSS sequence.
NOTE: The GSM command will only work if the base font is DP 10. See
the DECATFF command.
