square brackets in store procs cause crash - workaround

Hi, 4 separate stored procedures, when creating or executing caused online 7.23.UC7 to crash. I noticed a common thread in the 4 stored procedures [also none of my other stored procs cause crashes when creating or executing] and that is that all 4 use square brackets somewhere. e.g. if userid is a char(8) select * from foo where foo.userid[1,4] = "XXXX" Further, having replaced the square brackets with the alternative syntax: where foo.userid like "XXXX%" I have not experienced crashes so far. Anyone else seen this ? Peter Groarke
