SQL state 42601 FOR syntax error

Sir/Madam:

The code that follows iterates on a temporary table of distinct vehicle id's that results from a query on the normal.joined_points_speeds_orderedID table. The normal.joined_points_speeds_orderedid table has vehicle_id, trip_id, local_ts, calc_miles_duration, calc_time_duration, and calc_speed fields and is ordered by vehicle_id. The purpose of this code is to break up a large table of point level vehicle data by vehicle_id (into several smaller tables stored as csv). I think the code that follows should do this by copying temporary tables into csv files, however it doesn't. I get a FOR syntax error on the following code.

FOR rowNum IN SELECT DISTINCT ON (vehicle_id) vehicle_id FROM normal.joined_points_speeds_orderedID LOOP
EXECUTE 'CREATE TEMP TABLE vehiclePointData_'||rowNum|| 'AS SELECT * FROM normal.joined_points_speeds_orderedID WHERE joined_points_speeds_orderedID.vehicle_id='||rowNum;
EXECUTE 'COPY vehiclePointData_'||rowNum||'TO D:/PSRC_Public_access/calculations_points_speeds/'||rowNum||'.csv delimiters '||','||' WITH CSV HEADER';
END LOOP;

The Error reads-
ERROR: syntax error at or near "FOR"
LINE 1: FOR rowNum IN (SELECT DISTINCT ON (vehicle_id) vehicle_id ...

********Error**********
ERROR: syntax error at or near "FOR"
SQL state: 42601
Character: 1

Can you spot the error in the included code?

Thank you.
