[Zope-dev] Strings as input to the in tag: inconsistent

hi! i've posted this problem on the zope-list a couple of days ago with no reply so i'm trying zope-dev now: i'm using this code to output A B C ... Z: <!--#in "_.string.uppercase"--> <!--#var sequence-item--> <!--#/in--> this works fine in my Zope-1.10.2/Linux installation but Zope-1.10.2/Win95 generates this error message: Error type: InError Error value: Strings are not allowed as input to the in tag. can someone explain this inconsistency? why are strings allowed on linux but not on win95? thilo
