ISUBTOTAL= columns within item label for Table 27 |
This specifies what part of the data record is to be used to classify items for subtotal in Table 27.
ISUBTOTAL= file name |
file containing details |
ISUBTOTAL = * |
in-line list |
ISUBTOTAL = $S1W1 |
field in item label |
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 sub-grouping will be shown as "32/XT"
Format 2: ISUBTOTAL=*
This is followed by a list of sub-groupings, 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
or
@SGROUP=$S1W1
ISUBTOTAL=@SGROUP
TFILE=*
27 ; produce the subtotal report
*
Here is a subtotal report (Tables 27) for items beginning with "R"
