Thank you, Jay and Pavel.
So, there is much work going on "behind the scenes" in these two lines
because of the tightly-knit connection between TCL and SQlite:
proc sql_addnum { a b } { return [expr { $a + $b }] }

AIR/ActionScript?
proc sql_addnum { a b } { return [expr { $a + $b }] }

That is standard TCL rules and has nothing to do with SQLite.

Whilst trying to get a TCL script to create a function in SQLite I ran
into problems and did a lot of Googling. I got very tired of seeing the
same old same old...
proc sql_sqrt {x} {return [expr {sqrt($x)}]}
db function sqrt sql_sqrt
It didn't help me because it used only one parameter. It
