Re: MOVEA -> EVAL

["Peter Dow" <pcdow@xxxxxxxxx>]

Hi Barbara,

You're right, it's hard to think of a reason to use MOVEA these days, what
with all the nifty string handling stuff. Hmm. As I recall, some of the
things I once wanted to do with it I couldn't do anyway because it doesn't
allow

    MOVEA    arr1(m)    arr1(m + 1)

which could've been useful in shifting array entries down to leave an open
entry for insertion, or populating an array with some constant value (now we
have *ALL'x'). To do the above required something like

    MOVEA    arr1(m)    fld1
    MOVEA    fld1       arr1(m + 1)

The most interesting thing about MOVEA (to me) was the ability to go from an
array to a field and back. If you have fixed positions you could obviously
do this with overlaid data structure subfields, but MOVEA allowed it to be
variable. But it's been a long time since I felt the need to use it, and I
don't really remember specifics. (Usually when I say something like that I
have to use it the very next day<g>).
