Incrementing a field

Wanting to know if it possible to set initial value typeN of a field in
record 1 and then increment each record of that field by 5.
exp
field
record 1 1000
record 2 1005
so on

I am very new to foxpro but if it is possible i believe it takes code
which i would be place in the "'with" tab under the replace fields
button
TIA
