>Hi James, The second line looks strange. Is it a typo? llIskit = 0<RECCOUNT("MyComponents")

I would normally write it the other way: reccount(...) > 0; but apart from personal preference, I think it is perfectly valid.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
