I have a program that checks to see if a property already exists on an object before adding it, which would be the better way to determine if the property already exists?

    AMEMBERS( m.laPropertySet, m.loMyObject )
    IF ASCAN(m.laPropertySet,[cNewProperty],1,0,1,1)>0 && Case insensitive search, 0-not found
      ADDPROPERTY( m.loMyObject, [cNewProperty], [Test Information])
    ENDIF
    
    && or should I do this instead:
    
    IF PEMSTATUS( m.loMyObject, [cNewProperty], 5)
      ADDPROPERTY( m.loMyObject, [cNewProperty], [Test Information])
    ENDIF

What do you think?
