Preemptive apology (was Re: using variable in [Class create: aZone])

[Joseph & Kathleen Villa]

The answer was contained in the question: it's exactly like 
sel_get_uid(argSelector). After scrounging through objc-api.h, I found: 
Class objc_get_class (const char *name);

The proper functioning code looks like:

- (id) createAnObject: (const char*) argClass
{
        Class mClass;
        id mObject;

        mClass = objc_get_class(argClass);
        mObject = [mClass create: [self getZone]];
        return mObject;
}

Pretty cool stuff! Thanks all (and to Ginger Booth for her Tue, 29 Apr 97

Joseph.
