RE: MOVEA & Eval (was *Blanks and *Blank)

[Bob Crothers <bob@xxxxxxxxxxxxxx>]

So educate me...can and how do you do the equivalent of an MOVEA with 
an eval?

One of the problems of being an ISV is that you are always several 
years behind the rest of the world in the features you are using. 
 Since we have just recently raised the minimum os level we support to 
V3R1, we are just now starting to get into ILE.
