THIS SIGNALS COMPUTATIONS TO START.

THE FIRST CROSS SECTION NAME IN THE SERIES OF NAMES TO BE USED IN COMPUTATIONS.

THE LAST CROSS SECTION NAME IN THE SERIES OF NAMES TO BE USED.

INTERMEDIATE NAMES WILL BE SELECTED AS THEY APPEAR IN THE REACH FILE.

THE NAME OF THE CROSS SECTION WHERE STARTING ELEVATIONS ARE TO BE TAKEN. THIS
MAY BE THE SAME NAME AS THE FROM FIELD, OR THE CURRENT NAME IN THE STARTS OR
STARTE FILE OR A NAME IN THE TRIB FILE. IN THE CASE THAT THIS NAME OCCURS IN
BOTH THE START FILE AND TRIB FILE THE START FILE IS USED. IF THE NAME OCCURS
IN NEITHER THE START FILE OR TRIB FILE THEN COMPUTATIONS BEGIN AT CRITICAL DEPTH.
IF THIS IS LEFT BLANK THE SAME NAME AS IN THE FROM FIELD IS USED.

IF THE NO. OF SECTIONS IN A WATERSHED IS LARGER THAN THE PROGRAM LIMIT THIS WILL
ALLOW THE WATERSHED TO BE DIVIDED INTO SUBAREAS WITH EACH SUBAREA HAVING LESS SEC-
TIONS THAN THE PROGRAM LIMIT. THE SINGLE JUNCTION POINT BETWEEN SUBAREAS IS
ALWAYS A CROSS SECTION. THIS JUNCTION SECTION MUST BE LISTED ON THE TRIB CARD.
THE COMPUTE CARD WHICH FOLLOWS WOULD NORMALLY BE COMPUTE NAME 1 (FIRST REACH IN THE
NEW SUBAREA), NAME 2 , NAME3 (TRIB CARD). SINCE THE LINK CARDS MAKE ALL CROSS SECTION
DATA READ BEFORE THAT POINT UNAVAILABLE, SUCH THINGS AS A REACH2 DISPLACEMENT WITH
A SECTION DNSTM FROM THE LINK TO UPSTM FROM THE LINK IS IMPOSSIBLE.

USED WHEN UPDATING DATA FILES (SEE SPECIAL SECTION ON UPDATING)

THE NAME OF THE FILE TO BE CHANGED. FILES THAT MAY BE CHANGED ARE: REACH (IN-
CLUDES ROAD), SECTION, DISCHARGE, SEGMENT, TRIB, CONTR. BPR, CULV1.

NOTE: THE FOLLOWING FROM AND TO FIELDS ARE USED FOR THE 'REACH' FILE ONLY.

21-30

31-40

THE FIRST REACH TO BE CHANGED.

THE LAST REACH NAME TO BE CHANGED. ALL REACH DATA BETWEEN AND INCLUDING THE FROM
AND TO NAMED WILL BE DELETED. IF NEW DATA ARE DESIRED THEY MUST BE ENTERED
DIRECTLY AFTER THE CHANGE CARD IN THE ORDER THAT COMPUTATIONS WILL TAKE PLACE. IF
THE 'TO' FIELD IS LEFT BLANK THEN ANY NEW REACH (OR ROAD) CARDS THAT FOLLOW WILL
BE INSERTED IMMEDIATELY AFTER THE NAME IN THE FROM FIELD. THE DATA ASSOCIATED WITH
THE 'FROM' NAME ARE NOT ALTERED. IF DATA FOR ONLY ONE REACH NEEDS TO BE CHANGED
THAT NAME WILL APPEAR IN BOTH THE 'FROM' AND 'TO' FIELDS.

TO BE USED WHEN THE UPDATES ARE COMPLETED.

TO BE USED BETWEEN TWO WSP2 JOBS.

TO BE USED AFTER THE LAST JOB IN THE RUN (CALLS EXIT).
