A Patch to FOCAL W to use the LINC-8 Display
FOCAL8-58

This program is a patch for FOCAL W (8/68) which lets users
with LINC-8's use the LINC point display in FOCAL programs.
The user sets up and intensifies the X and Y coordinates
the same way as for the PDP-8 display except for the following
differences:

A. X and Y coordinates are reversed so that for example:

SET H = FDXS(X)+FDIS(Y)
should be rewritten as
SET H = FDXS(Y)+FDIS(X)

B. The range of X is from 0 to 51210
and the range of Y is from -25610 to +25610
The patch clobbers the ARCTAN FOCAL function. If the
ARCTAN function is needed, it can be computed from the
FEXP function.
