Normally, in a method, to set a SET statement, you would sometimes do:

lcSaveSetting = SET("TALK")
SET TALK OFF

* other code here

SET TALK &lcSaveSetting

Thats 3 lines of code just for one SET statement. Consider that in some cases
you would do this for multiple SET statements.

With this idea, you could have:

oTalk = CREATEOBJECT("SetCommand", "TALK", "OFF")

Thats 1 line of code. Seems reasonable to me.
