Re: identifying *ENTRY parms from a dump

["Carel Teijgeler" <coteijgeler@xxxxxxxxx>]

Hello  Dan,

Gene Gaunt wrote an utility to retrieve the entry parameters of a programme, 
IIRC. I downloaded it from www.iseriesnetwork.com (cannot remember year or 
month, or if it is still possible to do as not being a "Professional Member").

I have not used it yet (or looked at it), but it used an unfamiliar API (to me).

If Gene is on the list, perhaps he can verify this and elaborate on it.

If you are interested I can search for the downloaded code and send it to you.

Regards.
Carel Teijgeler
