Thanks for your ideas but I've decided to go with the scatter/gather memvar approach. It seems to work OK, but is there a quick way to empty out an array element without having to do the following:

store iif(vartype(laline[i])="C","",iif(vartype(laline[i])="N",0,iif(vartype(laline[i])="D",{},.f.))) to laline[i]

keeping in mind that I don't want the structure of the array changed in any way.

Thanks.
