RE: MOVEA -> EVAL

["Phil" <sublime78ska@xxxxxxxxx>]

I do this, for better or for worse:

Dindptr           s               *   inz(%addr(*in))
Dindicators       ds            99    based(indptr)
D Prompt                  4      4
D Refresh                 5      5
 . . .
D errInd                 30     39
D  errDate               30     30
D  errAcct               31     31
. . . .

I then initialize the errind subfield when necessary:
C                  eval        errInd = *all('0')

Oh, please no!  I had to maintain that type of code way back
when in QuickBasic.  I don't know why, but that code just doesn't
feel "right" to me.  I think because I've come across so many
compilers that don't follow the right to left rule.  Some do left
to right, in which case you would get different results.

I have always thought, though, that there should be some method
of setting/clearing/initialing more than one variable at a time
in languages, but I don't think that's the answer.

Maybe something like:
C                 Eval    Inz(*Off, *IN01, *IN02, *IN03, *IN04, *IN05)
would be nice, and would be very understandable and self explanatory.
But, the closest I've ever seen is the QuickBasic's method that you
show here.
