CHAPTER 16 USING THE TEXPLOT COMMAND
16.1 INTRODUCTION
The TEXPLOT command combines information from a TEX.QMS file
with information from the universal plot file and sends it to the
QMS Lasergrafix. The command accepts most of the qualifiers that
the PLOT command uses (see Chapter 15). Because the default
orientation for TEX files is protrait and the default orientation
for PLOT files is landscape, PLOT files that contain text may
have to be rotated by +90 degrees with the ROTATE qualifier. The
TEXPLOT command runs the program TEXPLOTCOM which parses the file
specifications and qualifiers in the same way that the VMS
operating system does.
16.2 COMMAND PARAMETERS
The format of the command is $TEXPLOT tex-file-specification
plot-file-specification.
The tex-file-specification specifes the file which contains the
device specific tex information for the QMS Lasergrafix. The
plot-file-specification specifies the file which contains the
universal plot information. Both files are required to have
their extensions which normally would be .QMS and .PLT.
16.3 COMMAND QUALIFIERS
The command qualifiers are listed below.
Command Qualifiers Default
/COPIES = number COPIES=1
/NUMBER = number Plots all plots on the
Lasergrafix
/ROTATE = angle ROTATE=0.0
/SCALE = scale factor SCALE=1.0
/XOFFSET = inches XOFFSET=0.0
/YOFFSET = inches YOFFSET=0.0
16.3.1 DESCRIPTION OF COMMAND QUALIFIERS
/COPIES=number
Specifies the number of copies of the plot which are
required.
Page 2
/NUMBER=number
Specifies which plot in a multi-plot file will be displayed.
By default, all plots in the file are plotted. Overlapping
plots in a multiplot file may be created on the Lasergrafix
if NUMBER=-1.
/ROTATE=angle
Specifies an angle through which a plot will be rotated.
Rotation takes place about the origin of the plot device and
occurs after offseting. A positive angle rotates the plot
counterclockwise.
/SCALE=scale factor
Specifies a factor by which the size of the plot is to be
multiplied. That is, /SCALE=0.5 will cause a plot to be
displayed at half normal size, /SCALE=3.0 will cause the
plot to be displayed at three times normal size.

/YOFFSET=inches
Specify offsets by which the plot will be shifted from its
normal position on the screen or paper. A positive value
shifts the plot either to the right or up.
16.4 EXAMPLES
2. $TEXPLOT/COPIES=3 TABLE1.QMS PLOT.OLD
Three copies of each plot in the file PLOT.OLD will be combined
with the TEX file TABLE1.QMS and printed on the LASERGRAFIX.
