Mike,

>Nope. If the method does IF ",VCXNAME.VCX," $ ','+SET('CLASSLIB')+',' it can be almost as fast.

Here I go again <g>

As you have more and more classlibs, that IF will become slower and slower, while NewObject should keep a relatively constant speed, for if we are not using classlibs and procedure files, there is nothing to open/close, so I am not sure. By the way, shouldn't you remove your commas? Set("Classlib") returns, for me, the full path of the library, like this "X:\FOXV\CLASSES\SKYFORMS.VCX ALIAS SKYFORMS, X:\FOXV\CLASSES\SKYCLASSES.VCX ALIAS SKYCLASSES". You can see that with only 2 classlibraries open the string is already quite long, and as you should not close any classlib open for what I said before, you might end up with a huge string to scan.
