> 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.
