functions for OS/8 BASIC. It allows up to ten overlays for the BASIC.UF
file and the first two fully utilize the features of the VT55 graphic terminal,
the DKC8-AA crystal clock, and a VERSATEC or LV-8 printer/plotter. It
can easily be extended to additional peripherals and the cursor control
functions will work with many types of terminals. The overlay swapping
function may damage unclosed (tentative) files.
