Re: How do I restrict a variable to a range of values?

[bofh_of_oz]

In two words: you don't.

In many more words: You can't restrict a variable from having any value it gets assigned. You can, however, write a validation block to check for valid values and complain|die|ignore the rest. I believe that's how it's being done in most cases...

You can't restrict a variable from having any value it gets assigned.

yes you can, using tie or at a lower level XS magic.
