I know. The grid is just always visible -- when you do an "insert",
"update" or "delete", it just doesn't display anything. Same for DDL.

The thing is, that this customer expects being able to run the EXECUTE
in this SQL Editor.

See above.

Yep. That's why I have a "run procedure" under the right mouse
click or in the Procedure Editor -> depending on whether the
procedure is an "executable" or "selectable", it displays a different
result window -> either a grid, or a param=value kind of grid-like

See above, yes -> just no display linked to the grid. The interface is
always the same.

Anyway, the documentation (IB) says that EXECUTE PROCEDURE
is available in DSQL, is that incorrect:

DSQL form:
EXECUTE PROCEDURE name [param [, param .]]
[RETURNING_VALUES param [, param .]]

I guess that some people could think that you could return a single
non-editable row from an EXECUTE as well.
