How can an error that Option Explicit would "catch" occur if the code is not changed? -- Microsoft MVP - ASP/ASP.NET - 2004-2007 Please reply to the newsgroup.

I guessASP code that doesn't run because of multiple Option Explicit statements can not have run time errors. -Paul Randall

It can't, unless... - There is a piece of code that has never executed in testing, but that could execute under certain conditions, or: - the code is self-modifying. The first should never happen in a script containing functions or class definitions. The second is to flirt with danger. That said, I always leave in the option explicit, because to take it out means modifying working code :-) Seriously, though, the only reason I see for ever wanting to remove option explicit is the situation posed by the OP, in which a piece of code is included in different contexts that handle option explicit differently. /Al |
