To be a little more correct FigForth v1.0 did indeed define
I and R (not R@) to share same code. My FigForth still does.
I believe R@ comes from one of the standards,e.g. Forth-83

AFAIK there was no R or R@ prior to FigForth.  MicroForth, Kitt Peat Forth,
'Starting Forth' simply used I for that.  It's unclear how FigForth came to
have R or Forth-79 came to have R@ .
