Oops, I am sorry for sending this message so soon after, but I just found it
out.
-(i.4)*]
Is the verb for me! Unless there are betters ways to do it, but that looks
good to me.
Are there better or standard ways of getting 100-200 for example.
I would do:
99+i.101
Or something like that, althought that only gives 100 - 199?
Thanks again,
Joey
