[comp.lang.apl] X11 for APL

ljdickey@water.waterloo.edu (L.J.Dickey) (11/29/89)

One of my colleagues has asked if I know of
any APL for which there is an X11 driver.

	I don't.

	Do you?

AT UNC we use STSC's APL*PLUS/UNX interpreter which supports a large
variety of terminal types via flexible input and output mappings.

STSC supplied us with X11 APL fonts that can be used with xterm and a
suitably arranged output mapping to yield an APL window.  The plain MIT
X11R3 xterm actually requires two fonts (-fn and -fb) to support all the
APL characters and overstrikes (recall quad-AV has 256 elements); 
DECwindows supports 8-bit character codes and hence dxterm can be used 
with a single font and a simpler mapping.

With this arrangement any workstation running X can host an APL window 
even though the interpreter, in general, runs on a different machine.
