> The argument values supplied to a PL/Perl 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/Perl function,
all values are just text strings.
