[TUHS] Re: ed: f command (facts vs. file)

https://www.bell-labs.com/usr/dmr/www/qedman.pdf (for DMR's QED for GE-TSS on the GE 635): _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.
