>     The argument values supplied to a PL/Tcl function's code are simply
     the input arguments converted to text form (just as if they had been
     displayed by a <TT
CLASS="COMMAND"
>SELECT</TT
> statement).  Conversely, the
     <TT
CLASS="LITERAL"
>return</TT
>
     command will accept any string that is acceptable input format for
     the function's declared return type.  So, within the PL/Tcl function,
     all values are just text strings.
