>     _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.
