Stored procedures

Hi folks ! I wounder how to find out if a stored procedure exist in the current database, i've looked thru all tables in sysmaster database, i did found one named sysprc, but that didn't seam to be the right one. And..... This question is real stupid one, but, is there any special things you must do when you use TStoredProc in delphi, with informix stored procedures, i can't get it to work at all. Maybe someone could give me a brief explanation how to use stored procedures in delphi. And finnaly. Some times i do get the following error in delphi, when i tried to edit a field in a table. The error says: "could not performe the edit becouse another user have changed the record", as you probably understand i'am rather new to the phenomen "database servers", we just converted our program from paradox, (hehe) to informix, and i have no experience from other database servers. I understand that i've done a very simple error somewhere but please explain to me what i've done wrong. Very greatful for any answer. --- John Gunnarsson ps. please send a copy to my mailboxes <it@jamtway.se>
