Kevin,
As far as I found out, it is done only once at the beginning. Just make
a test: set a stop point before the loop, and than make single steps
through the loop watching the local variables.
I use this for getting clear about efficiency from time to time, and I
found it a pretty
Gambas is open source, so you can always look in the source code how
everything is implemented. e.g. look in gbx_exec_loop.c and look for
jump_next.

Thank you everyone, that information is extremely useful. You can also
time several repetitions of the code and compare the results. It seems
declaration and pre computation of variables involved in a For...Next
loop isn't necessary other than for legibility, which is awesome.

Nested loops are of course different thing...

For Counter = 1 To 100

Does it make any difference if the
