Description Establishes the vertical physical size of the image on the display. Units expected (or
returned) vary according to the last mode set with USIZ command. The VSIZ command is
context sensitive and must appear between begin and end commands FMTB and FMTE .
The VSIZ? query returns the current setting of VSIZ.
Note: Make sure that the USIZ parameter is properly set before using the VSIZ command.
Changing the USIZ setting after entering VSIZ will convert the size to match the new unit
of measure.

new size into account.
