Dear All,

please try these couple of code in vfp6 and then in vfp7 as well.
select * from <>
? _tally
Dimension laTest(_tally)
? _tally
Display Memory like laTest

after executing these commands i assumed that laTest array variable will contains the number of elements, which was selected by the sql command.
in vfp6 this is the case
but unfortunatelly in vfp7 you will receive an array only with ONE element!!!!
it looks that the dimension command is also affect the _tally value.
or am i wrong?

thank you
Ivan
