I'm not sure if there is such a fuction, but I would like to know the C
function for blanking the screen. Many ACCs have it and I still haven't
found one that suits my needs. If anyone could post a message containing
this (if it's short) or e-mail me it (if it's long) I would greatly
appreciate it.
Thanks in advance.

How about printf("\x1BE"); or maybe Bconout(2, '\x1b'); Bconout(2, 'E'); which essentially is the same.

The UManitoba ether mailer has no idea where you are, so ...
Do you want to clear the screen or black it? Two different things. If the
latter, try saving the palette and resetting it to zeroes.
int oldpal[16], i;
int pal[] = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
for (i=0;i<16;i++)
oldpal[i] = Setcolor(i,-1); /* save old palette */
Setpalette(p); /* set new palette */
...
Setpalette(oldpal); /* restore original palette */
Note: This is off-top-of-head, untested code. Corrections welcome.
I have no idea how an STE or TT would react to this code.

How about using the `clear screen' VT52 escape. Can't think of it off-hand, but you should be able to find it documented somewhere. Or else some other netter with a better memory than mine (not difficult :-) ) might help you... (The good point about this method is that it takes virtually no programming: just a printf statement.)
