INTRODUCTION 1
The 3300/3500 COSY (compressed symbolic) task provides a means of compressing information in
a source deck by inserting special BCD characters to represent two or more consecutive blanks
on a card. COSY may be used with any source language that does not contain any of the COSY
control statements. Input and output may be in COSY and/or Hollerith format.
With COSY control statements the user may update and revise a COSY library and copy a COSY
library from one file to another. Because 3300/3500 COSY accepts blocked tape packed in 3200
COSY
format, the user can process COSY tapes prepared in the earlier 3200 format. Optional
log and revision listings may be specified for the output of a COSY run.

2.1
COSY LIBRARY
2.2
HOLLERITH
INPUT LIBRARY
COSy AND HOLLERITH ttBRARIES
A COSY library, on tape or on mass storage, consists of a group of COSY
decks in blocks of 1280 characters (320 words). A COSY deck is a series
of binary card images preceded by a BCD COSY deck identifier.
2
On a COSY library tape, the COSY decks are separated by end-of-file marks;
the library terminates with a double end-of-file mark. The MASTER trans-
fer function (XFER) must be used to transform unblocked tapes to the accept-
able blocked format (see MASTER Reference Manual).
The transfer function is not used for mass storage files. COSY prepares all
mass storage files.
On mass storage, a COSY library consists of a COSY-prepared directory
followed by COSY decks.
The directory is a 1280-character block containing a three-word entry for
each COSY deck on the file. Each entry consists of an eight-character
(left justified, blank filled) deck name and the number of the block in which
the deck identifier appears. The djrActory block holds 105 entries. If one
block is insufficient, COSY links another block with the first.
A Hollerith input library may be on tape, mass storage, or ,cards.
A Hollerith library also must be blocked in 1280 characters.
On tape, a Hollerith input library consists of a group of Hollerith source
decks, each separated by an end-oi-file mark. A double end-of-file mark
terminates the library.
This library must be on a non-standard data set identifier (dsi). No searching
is done on a Hollerith file; therefore, it must be positioned prior to entrance
to COSY.
COSY
accepts only one Hollerith deck per mass storage file. A deck ter-
minates with the last block written.

2.3
HOLLERITH
OUTPUT FILE
2.4
COSY
SCRATCH FILE
2-2
A Hollerith output file is a series of Hollerith source decks. When COSY
encounters ENDCOSY /, it writes FINIS and end-of-file records on the
Hollerith output file specified on the last DECK/ card. COSY then rewinds
the file or positions it to block one, ready for subsequent assembly or
compilation. The Standard Hollerith Output file (SHO) is also positioned to
block one. Blocked format of 1280 characters allows 15 Hollerith cards on
one block.
COSY reserves dsi COSY as a scratch unit for corrections. This system-
allocated file is used only if an excessive number of update records causes
internal table overflow.
The user should not use the dsi COSY for any other file, since all information
intended for this user file is placed on the COSY scratch file.

The processing of input and output under COSY is directed by the five user-
prepared control cards described below. If the user requests COSY output,
the COSY task prepares a deck identifier card (COSY /) as the first card of the
output deck.
When the deckname is used, it begins in column 1; the card name begins in
column 10, and parameter fields begin in column 20.
This card identifies the COSY deck and specifies the actions to be taken.
A revision deck for the named COSY deck may precede the DECI{/ card.
deckname Names the COSY or Hollerith deck to be processed.
A COSY deck may be on tape or on a mass storage file, or
may follow the DECK/ card on INP.
A Hollerith deck may be on tape or mass storage, or may
follow the DECK/ card on INP. Tape must be positioned to
the beginning of the Hollerith deck. COSY accepts only one
Hollerith deck for each mass storage file.
Specify the actions to be taken on the named deck. All seven
parameters are optional and may appear in any order on the
card. Parameters have the form:
name = dsi or name
Names are character strings beginning with I, L, R, H, C,
E, or T. Name length is limited only by the number of card
columns available.
dsi are alphanumeric strings of not more than four charac-
ters, the first of which is not *. dsi may be user-defined
or standard (INP, OUT, PUN). If a nonstandard dsi is
specified, the user must allocate and open the file, giving
it that dsi, before calling COSY.

.-;'."

SHO is the only nonstandard file that is not user-allocated. COSY allocates
and opens SHO using the system scratch pool.
1. . . specifies the dsi containing the input deck.
If the parameter is absent, or just 1. " is specifiep, COSY assu~, es
input is on the standard input file, ~ l c.. p-e~/f(:'klC ('; v1 ~OS'( /
If 1. " = dsi, COSY assumes the deck is on the named dsi. If dsi
is not INP and the first card image on the input medium is not a COSY
deck identifier card, the i,mage is assumed to be the first card of a
Hollerith deck. The Hollerith deck must be terminated with a tape
or card end-of-file, or with the last block written on the mass storage
file.
If dsi is not INP and the first card image is a COSY deck identifier,
then for tape, a forward search is made for the deckname, beginning
with this deck identifier. If a double end -of -file is encountered
without the deckname being found, the tape is rewound and searched
again. If the deckname is still missing, COSY prints an error
message on the OUT file, and reads the next control card.
For mass storage, if the file is not positioned to the deck sought,
COSY reads the file directory and positions the file. If the deck-
name does not appear in the directory, an error message is printed
on the OUT file and COSY reads the next control card.
L. . . Specifies that there is list output on the OUT file.
If the parameter is absent, there is no list output.

H. .. Specifies dsi to receive Hollerith output.
If the parameter is absent, there is no Hollerith output.
If H ... =dsi, output is on the named dsi. COSY assumes the output
medium is open and positioned.

If H ... = SHO or just H ... appears, COSY creates a scratch file
with dsi ~nless this file has been already allocated and opened
by a previous COSY run in the same job. Because SHO is released
at the end of the job, it should be used only if assembly or listing of
Hollerith output occurs in the same run. The user must schedule mass
storage scratch for SHO on the MASTER control card, SCHED.
C. . . Specifies the dsi to receive COSY output.
If the parameter is absent, there is no COSY output.

If just C ... appears, COSY output is on the~ile.
If C ... = dsi, output is on the named dsi.
E. . . Specifies the edition number of new COSY output deck.
If E is absent, COSY increases the edition number of the input COSY
deck by one (modulo 100) and inserts the new edition number in the
deck identifier card of the output COSY deck.
If E is absent and the input deck has no edition number, the edition
number on the output deck identifier is 1.
If E. .. = n (1::; n::; 99), the output deck identifier card has edition
number n.

nificant information on the input cards.

Interpretation of the T parameter depends on the type of output
specified, COSY or Hollerith, as shown in the following table.
