Dmitry,

The development environment here uses a set classlib environment that was cooked up to easily support classes on a per client basis where they want functionality different than the base functionality. One of these projects I work on has 82 classlibs in effect at runtime, and the len( set( "classlib" ) ) = 5216.

I don't know what the upper limit is. How big is yours? and what does occurs( ".vcx", lower( set( "classlib" ) ) ) return?

>The problem with set("classlib") is that it returns only so many characters (I didn't count exactly). I have tons of libraries. Therefore, chances are the library would be declared but not showing in the set("classlib"). That's why I would like to find out how resolve the problem in the first place.
>I think the issue is with SDT and I buy annual service contract from Stonefield so I should get the answer (I hope <g>). If not, I will follow your suggestion and place the question in the Stonefield section here on UT.
>Again, thank you so much for your help.
