Thanks Anders,

        Lucky was the operative word. I will find whatever howto suggested this 
in the
first place and convey the information. I think I still have the link
somewhere. Further experimentation shows, as always, you are dead-on:

alias tstinput='echo -e "\ntest\n\$2=$2; \n\$1=$1; \n\$3=$3\n"'
. .bashrc
13:19 alchemy~> tstinput one two three

test
$2=;
$1=;
$3=
 one two three

        Mystery solved.
