ISUBTOTAL= columns within item label for subtotals in Table 27

This specifies what part of the data record is to be used to classify items for subtotal in Table 27.

Format 1: ISUBTOTAL = $S..W.. or $S..E.. using the column selection rules.

$S..W.. e.g., $S2W13 means that the label to be shown on the map starts in column 2 of the item label and is 13 columns wide.

$S..E.. e.g., $S3E6 means that the label to be shown on the map starts in column 3 of the item label and ends in column 6.

These can be combined, and constants introduced, e.g,

ISUBTOTAL=$S3W2+"/"+$S7W2

If the item label is "KH323MXTR", the subgrouping will be shown as "32/XT"

Format 2: ISUBTOTAL=*

This is followed by a list of subgroupings, each on a new line using the column selection rules:

       ISUBTOTAL=*

       $S1W1+$S7W2                ; Subtotals reported for item classifications according to these columns

       $S3E5                        ; Subtotals reported for item classifications according to these columns

       *

Example:        Subtotal by first letter of item name:

               ISUBTOTAL=$S1W1

               TFILE=*

               27        ; produce the subtotal report

               *

Here is a subtotal report (Tables 27) for items beginning with "R"
