I don't want to hijack anything, but this is my burning issue today. I have cards that will become output; groups are copied from them to my output window, and then manipulated. It's also possible that cards will be added to that stack during program execution (there are a couple of hundred districts with their own forms). I'm waffling between something like if pg = 1 then put "group footer_1 " & " of " & tgCrd into tgGrp else put "group footer_c " & " of " & tgCrd into tgGrp end if if exists( tgGrp ) then copy tgGrp to outTarget do some other stuff with it end if The other approach would be to set a custom property full of this kind of information, and then at program load (or when another card is added) put the outControl of tgCrd into myTmp split myTmp by return and space put myTmp into outProps[the short name of tgCrd] and then the routine becomes if pg=1 then put "footer_1" into tgProp else put "footer_c" into tgProp end if if outProps[cdName][tgProp] is not empty then copy outProps[cdName][tgProp] of tgCrd do other stuff end if So if using the custom properties of a stack in memory is faster (even if having to parse the name?), then the first should be faster, while if a multi-dimensional array is faster, the second is faster. And I suppose there's a third, where I copy outProps[cdNam] to theProps, when beginning to render a form. I recall someone discovering that under some circumstances, it was worth the time to copy the subarray . . . -- Dr. Richard E. Hawkins, Esq.
