How to disable/ignore "pause"?

[Mojca M. <moj...@gm...>]

I'm sorry for a stupid question (probably not the most appropriate for
this list, but I didn't find the answer yet): how can I ignore
"pause"? I would like to call gnuplot from an external program (with
"set terminal whatever", has to produce a couple of graphics and then
exit quitely) and "I can't afford to hire a robot" to keep pushing
"enter" on pauses triggered with "pause -1"? Pause is good for
interactive terminals, but not when writing images into a file.

I would appreciate any hints,
