Compare results of SHOW PROC vs SHOW FUNC in ISQL:

SQL> set term ^; create or alter procedure p01(x int) returns (z int) as begin z=x*2; suspend; end^
SQL> set term ;^
SQL> commit;
SQL> show proc p01;
Procedure text:

begin z=x*2; suspend; end

Parameters:
X INPUT INTEGER
Z OUTPUT INTEGER

=== vs ===

SQL> set term ^; create or alter function f01(x int) returns int as begin return x*2; end^
SQL> set term ;^
SQL> commit;
SQL> show function f01;

Function F01:
Function library is
Entry point is
Returns BY VALUE
Argument 1: BY VALUE

Is it possible to display results for `SHOW FUNC` command in such manner as for `SHOW PROC` ? (i.e. show body and in-out arguments just like in SHOW PROC)
