I've verified this and it is now logged as PTS Bug B98507. Candy, what platform are you working on? Manufacturer, model (it doesn't have to be exact), O/S name and version, please. As you can see, the compiler appears to be treating 'FOR UPDATE' as a composite keyword, rather than recognizing 'END FOR'. There used to be a similar bug in I4GL where a CREATE TABLE statement followed by a LOCK statement would not compile because the compiler assumed the LOCK was part of LOCK MODE { ROW | PAGE }, a bug which is fixed in 7.20 I4GL (and possibly earlier).
