Re: Benefits of Sub-procedures




>>..what advantage do prototypes have over *ENTRY?

It is true that the PR/PI combination required to replace an *ENTRY PLIST
is more code, and might appear to be confusing.  I offer the following as
reasons to persist with the Prototype/Procedure Interface approach:

- all "declarative" coding appears on the D-specs - consistent and easier
to locate.
- D-spec format allows for more function through the Keywords section -
both at present and in the future (enhancements)
- specifically the OPTIONS, VALUE and CONST keywords for PR/PI parameter
definitions provide more function and flexibility
- avoids the need for fixed-format C-spec coding

Hope this helps.
