A closer look at microFORTH reveals it was also quite different from Forth
we know today.  There was no AGAIN or REPEAT.  UNTIL was called END.
Backslash '\' was COMPILE.  WHILE worked like REPEAT but resolved a
preceding IF/ELSE.  FILL had no resemblance to today's word.

In comparison Fig-Forth, which came out not long after, looks relatively
modern.  So while Fig-Forth's origin may have been microFORTH, its
influences appear to have extended well beyond.
