GENERAL DESCRIPTION
The 1401/1460 Coda and Dolete/Extract program is a file rnanipulation program
that purforms any cornbination of the following functions:
1. REFORMATING
The fields within the input records may be re -arranged to form
output records of a different format and length. Fields of constants
rnay also be added to each output record.
2. CODING
Data may be inserted into only those records which have fields
lying within certain ranges established by the user. The data to be
inserted may be contained within the record itself or may be supplied
by the user.
3. DELETING/EXTRACTThJG
Records with fields lying witpin specified ranges may be selected and
written on tape and/or listed on the 1403 printer (DELEXOUT output
file). A second output file is available which will cOhtain either all
records that were on the input file (extracting) or only those records
which were not selected (deleting).
4. LIST B MATCHING
A second bput file may be used to match on a given control field
against the Master input file. On an equal oondition, data from the
List B record will be moved to the output area; or List B may be
used as a finder file to delete or extract records on the Master input
file. If List B is used, both input files must be in ascending sequence
on the control field used for matching"
SPECIFICATIONS
1. MACHINE
The Code and Delete/Extract program requires a 16K 1401 with
Advanced Programming and High-Law-Equal compare, 1402 reader-
punch, .1403 printer with 132 print pOSitions, and from 2 to 4 tape
units..
2. FILES
All files must consist of fixed length records, blocked or unblocked.
Data record length may not exceed 1000 characters for any file" There
is no restriction on tape record length for any individual file; however,
'til
- 2 -
the sum of tape record lengths for all files may not exceed 8200 charac-
ters. The program will accept, for the two input files, any type of
header label with or without tape marks, or no labels at all. Standard
7080 labels, or no labels, may be generated for either or both of the
two output files.
3. RECORD COUNTS
At end of job, the program will print data record counts for all input
and output files, the nurnber of records coded, and the number of equal
comparisons to List B ..
PREPARATION OF CONTROL Cj~.RDS
The following describes the preparation of the AKB210 control card layout forms
for keypunching. Unless otherwise specified 1 unused control card columns should
be left blank. The program will print out each of the user I s control cards after
the housekeeping associated with it has been performed. Note that in the hierarchy
of operations performed by the program, the input record is reformated before
any matching to List B, coding, or deleting/extracting is performed. Therefore
any reference to Master Input File fields in the control cards (other than those used
for reformating) must refer to these fields as they will appear after reformating
is executed ..

Note: there is no maximum length for any individual file,
but the sum of tape record lengths of all files must not'
exceed 8200 characters.

to have 7080 standard header labels.
31 input labol code:
x = hoader followed by tape mark

output label code:
x = standard 7080 header and trailer
o = no header, standard 7080 trailer
- = no header, no trailer
32 - 33 number of input reels 01 - 99
If actual number of records is punched, this will determine
EOF. If unknown, punch 99 and EOF will be designated by
sense switch setttng at execution time.
34 List B option
F = data from List B will be added to the output record
C = matching control fields on a Master record and a
List B record will cause the extraction of the Master
record.
D = matching control fields on a Master record and a
List B record. will cause the deletion of the Master
record.

file will already have been put in the output area by the reformat routine.

NOTE: Data not contained in the Master input record may be inserted
into every output record by using the Additiona+ Information option:
where the Master input high order position would normally be
specified, enter AI xx - where xx is the high order column of the
"6M" card containing the data to be entered.. A. maximum of
10 fields of additional information may be added into every
output record.,

tests - tho maximum number of range tests is 40. Any range test may
have equal upper and lower limits.

4 range tests relationship code
1 = OR range tests - record will be selected if any
range test is satisfied (test 1 or test 2 or test 3, etc.)
2 = AND range tests - record willte selected only if
two successive range tests on the same control card
are satisfied (test 1 and test 2)
5-- 6 number of characters in field to be tested.

27 - 48 field 2, if required
49 - 70 field 3, if required (OR tests only)
CARDS 2 - 8 fields 4 - 25 as required
NOTE: If more than two conditions must be associated by the
"A.ND" relationship;, a control word may be set up in the coding
phase with one position on or off for each condition; the whole
word may then be tested in the delete-extract phase.
The following examples show how the various
options available in A.KB210 can be exercised .
