Columns 13-17
Largest Sum
Columns 13 through 17 specify the largest sum of control field lengths of
any record section (in bytes).
The entry requires the following calculations:
a. Compute the lengths of all control fields on Field Description specs
(when column 7 is N, O, or F--see table below). Sum these totals
separately for each record section (see definition of "Sections" on
page 5-3).
b. Place the largest of these sums in columns 13-17. The entry cannot
exceed 256.
Additional information concerning this entry can be found under column 7
of the Field Description Specifications. Also, see figure 2-1, in which
the largest control field sum of two record sections is calculated and
the total entered in columns 13-17.
In computing the total lengths of control fields and work records the
following guidelines should be noted:

(columns 9-16).
