> _History of QED_
> The original QED was implemented at the University of
> California, Berkeley [4]. Substantially redesigned versions
> were written by the second author (KLT) for the CTSS system
> at MIT [1] and in BCPL for MULTICS. The latter version has
> also been available under GE-TSS using I/O routines supplied
> by A. W. Winikoff.

> _This version of QED_
> The present incarnation of QED was implemented in GMAP by
> the first author (DMR). It offers noticeable improvements
> in speed, program size, and text packing density over the
> BCPL version, of which it is a direct descendant. New
> facilities include a redesigned Global command and a
> numerical capability
>
> The F(acts) command appears on page 9 (pdf page 10)
>
> The F command causes QED to type out
> 1) the number of words on QED's "free list",
> 2) the highest memory location used for text storage, and
> 3) the current core allocation.
>
> When the third number gets near 32K, take care not to exceed the core
> maximum.
