Or, more likely, work out why you don’t really need to increment and
use something else (hint, if you’re incrementing an array index,
you’re probably doing it wrong)

Take a look at Ruby-Doc.org: Documenting the Ruby Language
which includes “To increment a number, simply write x += 1T.”
Hope this helps,

You may also say
someVar = someVar.succ
With strings even this works:
str = “A0000”
str.succ!
For iterating use somethig like Fixnum#times or Array#each.

Teodor, if you now start wondering why there is no i++ in Ruby please
see the recent thread “Ruby doesn’t implement x++ for Fixnum’s because
???”.
