>Thank you all very much for your help in this matter. The only problem is that I'm going to have sleepless nights until I find out what the difference between () and & is - but that isn't a question for you guys. I'll search around to find the answer to that one. Thanks again.

Tony,

Run the following test:

local i, lnSec
lnSec=seconds()

for i=1 to 100000
   if type('oJC')='O'
   endif
next

?seconds()-lnSec   
lnSec=seconds()

for i=1 to 100000
   if vartype(oJC)='O'
   endif
next
?seconds()-lnSec

Vartype works two times faster, than type.
