Re[2]: Creating a service program

     Yes, in fact the only restriction is having only one *current 
     block. Someone just posted a link to an article that explains this 
     very well. Check it out.

Curiosity question on this.  Okay, now you have 2 signatures in your binder lang
ge, one
*PRV for the old calls, one *CURRENT for the new calls.  What do you do when you
dd
a few more procedures to your directory?  You can't have 2 *PRV can you?
