Ignoring the *IN99 (gag!), I wouldn't use either one.  In this particular
case I would use
   clear    eqsize
It's not going to make any difference performance-wise as they probably
generate exactly the same W-code.  move  *zeros   eqsize  would probably
generate the same code as well.

My personal preference is to use clear when setting a field to *blanks for
character fields or *zeros for numeric fields, and to otherwise use eval.
