******************************************************************
* RSP4C - DOCTORED STORED PROCEDURE *
* *
* THIS SAMPLE STORED PROCEDURE WAS WRITTEN TO USE A "STD" *
* OUTPUT PIPE AND KEYWORDS FOR ILLUSTRATION. IT REQUIRES AT *
* LEAST ONE KEYWORD/VALUE BE PASSED TO IT WHEN INVOKED.
*
* *
* USE PROCEDURE RSP4C &FIRSTKEYWORD=FIRSTVALUE ; *
* *
* THIS PROGRAM IS SET UP TO ACCEPT KEYWORDS OF UP TO 15 CHARS *
* IN LENGTH AND UP TO 28 CHARS FOR THE KEYWORD VALUES. ALL *
* KEYWORDS, KEYWORD VALUES, WILL BE RETURNED *
* THROUGH THE OUTPUT PIPE AS VERIFICATION. *
* *
* ALSO: 2 SPECIAL KEYWORDS ARE SET UP TO TEST ERROR MESSAGING *
* THE ERROR CONDITIONS SEND 'E' TO SPSTATUS *
* - ONE USING "MESSAGE" AND ONE USING "STATUS". *
* &ERRORMSG : 'E' TO SPSTATUS, MSG TO SPMSG, CALLS 'MESSAGE' *
* &MESSAGE : 'OK'TO SPSTATUS, MSG TO SPMSG, CALLS 'MESSAGE' *
* &STATUSMSG : 'E' TO SPSTATUS, MSG TO SPCODE, CALLS 'STATUS' *
* &STATNEMSG : 'OK'TO SPSTATUS, MSG TO SPCODE, CALLS 'STATUS' *
