RE: Strange behavior w/%editc()

[rob@xxxxxxxxx]

I think it goes back to ancient processors and bit twiddlers who determined
that a move might be less processor intensive than multiplication.  So to
multiply by 10 you MOVEL a number into a field that is 1 digit bigger.
I've never used this.

Did I miss a meeting?  :)
When did the MULT operation code and MOVE/MOVEL get merged? This is the
second reference condemning MOVE/MOVEL in this tread that uses MULT as
the validation for that condemnation.
