Hi Gary,

You're on the right track... just a few modifications.  Try the following:

! mytest.jnl
\can mode verify
IF  $3"False|*>True" THEN
  say $1.$2.$3
ELIF $2"False|*>True" THEN
   say $1.$2 
ELIF $1"False|*>True" THEN
   say $1
ENDIF
set mode/last verify


Here's what happens when you run this script:

yes? go mytest
yes? go mytest hello
hello
yes? go mytest hello there
hello.there
yes? go mytest hello there Gary
hello.there.Gary

Hope that helps,

Andrew
