We recently bought Versaterm Pro for the MacII
and I've been using it for tektronix emulation
to get nice graphics output for some C programs
I wrote for my thesis on the local Vaxen.
(Programs do big genebank searches on the vax,
make graphic output in tektronix langauge, i do
screen capture on the mac end and paste into mac
graphics programs.) Now, all I know about tektronix
is what I find in the relevant man sections of the
unix plot function. It tells me how to make lines,
circles, arcs and stuff and even a few line modes
like dotted and dashed. However, the versaterm manual
refers to an least 7 line styles, text styles, and
fill patterns and shows how to use them for nice color
output which would be really spiffy to put in my
otherwise dull-looking thesis. Problem is, I cannot find
clue 1 as to how to call these functions from within
the programs. Is there some set of functions like

	openpl();
	filltype("crosshatch");
	linestyle("red");
	filledbox(x1,y1,x2,y2);
	closepl();

that are described somewhere that i can find?
i guess i could do a lot of this with pic
(still would like to get the color, though)
but i basically need to get it up on the screen
for easy transfer to the wonderful world of mac graphics.
can anybody point this only semi-compu-literate
biochemist in the right direction?
thanx
