5. Assign the two integer segment of the CFCC to the major1 item of each record in the
modified frequency file:
Arc: info
ENTER USER NAME> ARC
ENTER COMMAND> SELECT ROADS.FRQ
ENTER COMMAND> UPDATE
RECNO?> 1
CASE# = 1
FREQUENCY = 5678 (this value and the cfcc code are examples)
CFCC = A01
MAJOR1 = 0
?> MAJOR1 = 01 (there must be a space on either side of the =)
?> <cr> (carriage return)
RECNO?> 2
CASE# = 2
FREQUENCY = 456
CFCC = A12
MAJOR1 = 0
?> MAJOR1 = 12
?> <cr>
Proceed through the remainder of the records until all CFCC occurrences have a major1 value
associated with them. After the last record:
RECNO?> <cr>
ENTER COMMAND> LIST (to check the file. The major1 values beginning with a zero
will only be saved as the second digit. It is assumed the user of the DLG file will be able to
interpret the single digit value as being preceded by a zero.)
ENTER COMMAND> Q STOP
6. Use the modified .frq file as a lookup table to assign a major1 value to each record in the
coverage according to its CFCC item value:
Arcedit: edit rd_for_dlg arc
Arcedit: select all
Arcedit: lookup major1 major1 roads_cfcc.frq cfcc
Arcedit: save
7. To check the results, another "frequency" can be executed to determine the combina-
tions of both the CFCC and the major1 items. There must be a 1:1 correspondence:
Arc: frequency rd_for_dlg.aat rd_check.frq
Enter Frequency item names (type END or a blank line when done):
Enter the 1st item: cfcc
Enter the 2nd item: major1
Enter the 3rd item: end
Enter Summary item names (type END or a blank line when done):
Enter the 1st item: end
Arc: list rd_check.frq
8. Create a text file describing the contents of the major1 item (or add to the metadata file).
