Changing types

Hi,
can anyone tell me wat s the command that can be used to change the type of a module.
For eg,
i want to change module which is subprogram to a subroutine, which should have the same name.

Type the following on the editor’s command line:

set type S

or N for Subprogram, or P for Program and so on.

EDIT: And here is the link to the documentation:

The RENAME command has an option to change the source module type.

One caveat to RENAME - you can only change the type if the object code does not exist.
