Unit of measure used for physical SIZes
System control
Sets the units of measure assumed by
physical size of the image that appears on the CRT (context sensitive; see
FMTE). The USIZ? query returns the current setting of USIZ.
Note: Changing the USIZ parameter between inches and millimeters will convert the
current HSIZ and VSIZ values to match the new unit of measure. For example, if USIZ is in
inches and the current HSIZ is 10 (inches), changing USIZ from inches to mm will change
HSIZ to 25.4 (mm). The USIZ command should be sent before specifying physical sizes in
format command files.
