:zztech: PROGRAMMATIC ARGUMENTS (was Re: [zigzag] Re: Jump Cursor exists (was Re: [zigzag] Re: Okay, I've figured out



Ha!  

Fab!  (See, I'm up-to-date and Hep!)

If cells are to accept programmatic arguments,
 they should be in a cell adjacent +d.2
 to the invoking cell.

By cloning the cell, containing the cell, and/or
 using the as-yet-unimplemented d.execute,
 a parameter may be supplied to the particular
 instance of the progcell.

Best, T
