: Yeah, but doesn't fit my needs. If it fails the [if] then control
:flows to:
:
: } else {
: switch -- $num {
: 2 { # ^B routine }
: 3 { # ^C routine }
: ...

  Ok, not making good sense here am I? I need to do some more tests
and get a better understanding of [string is <ascii|print|control>]
because I know they weren't working out for me in the particular
proc I was writing.

  It should work to use them in a multiple [if] and then use [scan]
if needed to get the integer vakues.
