Files in directory src/uwfocal from the latest check-in of branch trunk
FOCAL, the FORmula CALculator was an early interpreted language, pioneered on the PDP-8.
We have a historically accurate FOCAL69 package elsewhere. The University of Washington extended FOCAL significantly. This package is the latest version found of that work, U/W FOCAL.

Unfortunately the archive is incomplete.
Assembly instructions found in 16KCPR.PA, say:
/ UWF.BN<16KCPR,12KFNS,8KFIO,8KFPP,16KLIB/L/K=100 / EAE VERSION: 8XFIO,8XFPP
The non-EAE versions of FIO and FPP have been lost.
The assembly, load, and save lines used are:
UWF16K.BN<16KCPR.PA,12KFNS.PA,8XFIO.PA,8XFPP.PA,16KLIB.PA/K LOAD RKA1:UWF16K.BN SAVE RKA1:UWF16K.SV;100

Additional explanations of how to use U/W FOCAL under SIMH have been crafted
As of this date, every version of FOCAL I've tried can't accept paste-in from other windows. The characters come in too fast and overrun the input buffer.
I do not like U/W FOCAL's approach to program load and save.
However this archive should build, run, and allow overlays following instructions in NOTE1.TX, NOTE2.TX.
