Re: Passing By Reference

You can change storage that's passed by reference...   In fact, that's the
normal way to pass a variable that you want to change, you pass it by
reference.

Something else must be going on here.  Maybe you're accessing data beyond
what you passed?  For example, if you passed a *varsize variable, and then
did a 'eval variable = *blanks' that would overwrite memory past the end
of the variable.

Can you post the code?
