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

That looks like a MOVE, not a MOVEA.

In the C world, a MOVE is loosely equivalent to a a(1) = ' ' (set 1 
element to a ' ') where a movea is equivilent to a memset(a, 0, 
sizeof(a)); (set entire array to hex 0)

eval a(1) = ' '
eval a = ' '

Coming from a pc background, I recognize ' ' and prefer not to use
*BLANKS (or *BLANK).
