Hi Nadya.

>Thanks. I sporadically have problem "ALIAS name is already in use" on set classlib command. Does it need to check, if this file is alredy in SET('CLASSLIB')?

That error is caused by SET CLASSLIB to a class library with the same name as one already open but in a different directory (eg. you have two different MYCONTROLS.VCX, one of them is already open, and you're trying to SET CLASSLIB to the second one).
