NAME
dpsexec - Display PostScript Executive
SYNOPSIS
dpsexec [ -display name ][ -sync ][ -backup ][ -noexec ][
-root ][ -drawable windowId ][ -height n ][ -width n ]
DESCRIPTION
dpsexec is a Display PostScript program that allows the user
to interact directly with the PostScript interpreter through
a command interface. dpsexec reads lines of text from stan-
dard input and passes each line to the PostScript inter-
preter for execution. It creates a window that displays the
results of graphics operations as they are executed. dpsexec
exits when end of file is reached on standard input, or when
the user types "quit<return>", which executes the PostScript
quit operator.
By default, dpsexec executes the PostScript executive opera-
tor before it accepts any user input. This operator puts the
PostScript interpreter in "interactive executive" mode so
that the user can control the interpreter directly. In this
mode, the PostScript interpreter supports certain line-
editing functions and prompts the user when it is ready to
execute more input. See section 2.4.4, "Using the Inter-
preter Interactively," of the PostScript Language Reference
Manual, Second Edition, for detailed information on this
mode of operation.
OPTIONS
-display name
specifies the display on which to open a connection to
the Display PostScript system. If no display is speci-
fied, the DISPLAY environment variable is used.
-sync
establishes a synchronous connection with the specified
X display.
-backup
uses backing store for the window in which graphics are
displayed, if possible. This is generally only effec-
tive with the DPS NX system.
-noexec
prevents dpsexec from entering "interactive executive"
mode. The primary effect of this option is to inhibit
printing the PS> prompt before each line of input is
accepted. This option is useful when dpsexec is run

of into a window that it creates.
