QMS VMS Software Manual page 91

Bold displays the time and date of printing on the left, the filename
centered in the middle, and the page number on the right. The header
baseline is 0.5" from the top of the page, and has left and right mar-
gins of 0.5". The main body of text has a top margin 1" wide, a left
margin 0.75" wide, and a bottom margin 0.5" wide. The right margin is
determined by the right limit of the printer's imageable area. The
fonts, point sizes, margins, orientation, line spacing, and several other
parameters can all be altered by the user by means of command line
options.
prtpost reads command line options in standard UNIX style: options
come between the command name and the file argument, and each
option is a one- or two-letter code preceded by a - character. If an
option takes an argument, it may immediately follow the option code
or be separated from it by a space. The arguments are provided to
the symbiont in a queue logical much like the /PARAMETER logical
QMS$ queue_name _QUEUE. This logical must be named
QMS$ queue_name _NUP. For example,
$ DEFINE/SYSTEM QMS$ASCII2PS_NUP "-L -2 -N"
$ INITIALIZE/QUEUE/START/GENERIC=QMS_2025 ASCII2PS
$ PRINT/QUEUE=ASCII2PS QMS$HEADERDOC.PS
Job QMS$HEADERDOC (queue ASCII2PS, entry 8) started on QMS_4525
means print file QMS$HEADERDOC.PS in landscape orientation, 2-
up printing (two pages on one side of the sheet of paper), with no
header. Next a generic queue ASCII2PS (ASCII-to-PostScript) is cre-
ated. This queue is pointing to the preexisting execution queue,
QMS_2025. The option codes are cryptic, and there are many of
them, but they offer you a high degree of control over the printed out-
put. If you only want to use a few of the options, symbols can be writ-
ten defining the logical for frequently used option combinations.
Margins and point sizes are specified in decipoints, where one deci-
1
point is / ". For point sizes, this amounts to multiplying by 10. For
720
example, -F120 was used to select 12 point type above. Margins are
measured in the default PostScript coordinate system: The origin is at
the lower-left corner of the page, x increases to the right, and y
increases upwards. For example, the upper-right corner of an 8.5" x
11" page would have an x coordinate of 6120 and a y coordinate of
7920.
