I don't understand the command '&' that the alias uses. NOR DOES DBX!
Please excuse me if I am missing something very basic, but I put these
aliases in my .dbxinit and when I typed:
(dbx) F(aray,3)
I got from dbx:
&((!1[0])//!2 F(aray,3)
^ unrecognized command
(dbx)
Yes, I did include the '\' in the definition.
This was attempted in Ultrix and SunOs 4.0.
