Speaking of weird BASIC features, does anyone know why DECSYSTEM 20's BASIC had a "LISTREVERSE" command?
Yes, it actually did exactly what it sounds like!
Chalk one up for DEC and BASIC. What other programming languages support that feature, huh?
DECSYSTEM 20 BASIC User's Guide: LISTREVERSE command
LISTREVERSE
LISTNHREVERSE
LISTREVERSE and LISTNHREVERSE print the contents of the
user's memory area in order of descending line numbers.
LISTREVERSE precedes the output with a heading,
LISTNHREVERSE eliminates the heading.
LISTREVERSE
EQUIV 10:53 13-NOV-75
40 END
35 PRINT "THE EQUIVALENT CURRENT IS",I, " AMPERES"
25 I=E1/R
10 INPUT R
5 INPUT E1
READY

If you're using a printer, presumably you might sometimes want the stuff at the top of the program to be last on the printout, so it's easy to get at without having to flip through a pile of paper?
Same might go for a terminal with no scrollback...
Come to think of it, this sounds actually rather useful. Had this been available when I was programming on the BBC Micro, I bet I'd have used it.
Emacs should have an edit-reverse-mode!
