STATUS in Informix-4GL is the result of executing an SQL statement.
It is set as follows :
* To 0 for a successful execution
* To NOTFOUND (100)
* To a negative value for an unsuccessful execution
However for UPDATE statement, finding no row that
satisfies the condition, is considered as a SUCCESS,
i.e. STATUS is set to 0 but sqlca.sqlerrd[3] tells
how many rows really updated, using that count, action
can be taken AS in this case,
if STATUS (w_status) is 0 and sqlca.sqlerrd[3] (c_upd_rowcnt) is 0 too, no
row is found
so INSERT into the table.
