Geoff,

your replies are always so elaborately - they are really helpful, thanks a
lot.

With a closer look to provided array example I could solve my problem by
myself. GetVarSlice is the right way but I had to assign variant array in
right manner...

BTW, I was using Interbase without arrays more then 3 years but now I've to
provide a simple side calaculation to an integer column with a sum of max.
10x2 multiply. For these purpose I temporarily show a TIB_ArrayGrid in a
TIB_Grid and is working perfectly. Much quicker and easier to maintain then
a master/detail relationship.

Mit freundlichem Gruss & Best Regards
