PGPLOT Module: PGASK -- control new page prompting


SUBROUTINE PGASK (FLAG)
LOGICAL FLAG

Change the ``prompt state'' of PGPLOT. If the prompt state is
ON, PGPAGE will type ``Type RETURN for next page:'' and will wait
for the user to type a carriage-return before starting a new page.
The initial prompt state (after the device has been opened) is ON
for interactive devices. Prompt state is always OFF for
non-interactive devices.


Arguments
FLAG (input) : if .TRUE., and if the device is an interactive
device, the prompt state will be set to ON. If
.FALSE., the prompt state will be set to OFF.
