Jim,

So if we have intense code loops to run that aren't using any table/cursor data, we should do a SELECT 0 to move to an unused work area before the code starts executing. It kinda makes sense that that would give us the highest possible preformance.

Since his code uses 255 fields, it represents the worst case; halving that number will roughly half the amount of the increase, and so forth down to 1 field. With 1 field, or no table open in the currently selected workarea, there is basically no slowdown, or it is negligible.
