C     PROGRAM SURVEY
C
C     DESCRIPTION
C	THIS PROGRAM READS CODED RESPONSES TO A QUESTIONNAIRE AND WRITES
C	THEM INTO AN ASCII DATA FILE.
C
C     SOURCE
C	NORMAN W. JOHNSON, DEPARTMENT OF MATHEMATICS, WHEATON COLLEGE,
C	NORTON, MASS.
C
C     INSTRUCTIONS
C	THERE SHOULD BE NO MORE THAN 128 QUESTIONS.  RESPONSES MAY BE
C	CODED BY ANY DIGIT FROM 0 TO 9.  ADDITIONAL SYMBOLS THAT MAY BE
C	USED ARE THE MINUS SIGN (-), THE AMPERSAND (&), AND THE BLANK,
C	INTERPRETED RESPECTIVELY AS THE NUMBERS 11, 12, AND 13.  THESE
C	SHOULD BE RESERVED FOR SUCH CATEGORIES AS "NOT APPLICABLE",
C	"DON'T KNOW", AND "NO RESPONSE".
C
C	THE FIRST 5 COLUMNS OF EACH DATA CARD ARE FOR IDENTIFICATION,
C	WITH THE FIRST 4 COLUMNS BEING UNIQUE TO THE RESPONDENT.  THE
C	NEXT 67 COLUMNS OF THE CARD ARE FOR THE CODED RESPONSES, ONE
C	COLUMN PER QUESTION.  THE LAST 8 COLUMNS ARE NOT USED.  IF THERE
C	ARE MORE THAN 67 QUESTIONS, A SECOND CARD FOR EACH RESPONDENT
C	MAY BE PREPARED IN THE SAME MANNER.
C
C	THE SET OF DATA CARDS MUST BE PRECEDED BY FIVE OR SEVEN PROGRAM
C	CARDS.  THE FIRST OF THESE HAS PUNCHED IN ITS FIRST 5 COLUMNS
C	THE NAME THAT THE DATA FILE IS TO HAVE.  THE SECOND MAY BE USED
C	FOR A DESCRIPTION OF THE SURVEY (NOT MORE THAN 48 CHARACTERS).
C	THE THIRD CARD SPECIFIES THE NUMBER OF QUESTIONS (ANY FORMAT
C	IS ACCEPTABLE).  THE LAST TWO CARDS OR PAIRS OF CARDS, PUNCHED
C	IN THE SAME FORMAT AS THE DATA CARDS, INDICATE RESPECTIVELY THE
C	LOWEST NUMBER AND THE HIGHEST NUMBER TO BE COUNTED AS A RESPONSE
C	TO EACH QUESTION.  NUMBERS OUTSIDE THIS RANGE ARE TREATED AS "NO
C	RESPONSE" AND EXCLUDED FROM THE TOTAL.  ON THESE CARDS BLANKS
C	AND MINUS SIGNS ARE EQUIVALENT TO ZEROS, AND AMPERSANDS MAY NOT
C	BE USED.
C
C	THE LAST DATA CARD MUST BE FOLLOWED BY A SINGLE BLANK CARD OR A
C	PAIR OF BLANK CARDS, ACCORDING AS ONE OR TWO CARDS ARE USED FOR
C	EACH RESPONDENT.
C
C	THIS PROGRAM ASSUMES THAT INPUT IS FROM THE USER TERMINAL AND
C	OUTPUT IS TO THE DISK.  IF A DIFFERENT INPUT DEVICE, SUCH AS THE
C	SYSTEM CARD READER, IS TO BE USED, IT SHOULD BE ASSIGNED LOGICAL
C	UNIT 5 PRIOR TO RUNTIME.  ALSO, FOR INPUT FROM THE CARD READER,
C	THE USER SHOULD RESPOND TO THE PROGRAM'S REQUEST FOR DATA BY
C	TYPING "@CDR:".  FOR INPUT FROM A FILE ON THE DISK, THE USER
C	SHOULD TYPE "@DSK:FILNAM.EXT", WHERE 'FILNAM.EXT' IS THE NAME
C	OF A CARD-IMAGE SOURCE FILE.
C
C     SPECIAL INSTRUCTIONS FOR NONSTANDARD SOURCE DECKS
C	DATA CARDS DO NOT NEED TO BE PREPARED IN EXACT ACCORDANCE WITH
C	THE ABOVE INSTRUCTIONS TO BE ACCEPTABLE, PROVIDED THAT (1) THERE
C	ARE NO MORE THAN TWO CARDS PER RESPONDENT, (2) EACH CARD CON-
C	TAINS AN IDENTIFICATION LABEL, AND (3) THE ONLY RESPONSE CODES
C	USED ARE DIGITS, MINUS SIGNS, AMPERSANDS, AND BLANKS.  WHEN A
C	NONSTANDARD SOURCE DECK IS INPUT, THE PROGRAM CARD SPECIFYING
C	THE NUMBER OF QUESTIONS MUST BE REPLACED BY A FORMAT CARD GIVING
C	THE BLOCKS OF COLUMNS IN WHICH IDENTIFICATION AND RESPONSES ARE
C	PUNCHED ON EACH DATA CARD.
C
C	FOR EXAMPLE, IF THE SOURCE DECK CONTAINS ONE CARD PER RESPONDENT
C	WITH RESPONSES PUNCHED IN COLUMNS 1 THROUGH 72 AND IDENTIFICA-
C	TION IN COLUMNS 74 THROUGH 80, THE FORMAT CARD SHOULD READ:
C		74-80,1-72
C	FOR A SOURCE DECK CONTAINING TWO CARDS PER RESPONDENT, HAVING
C	IDENTIFICATION IN THE FIRST 4 COLUMNS OF EACH CARD AND RESPONSES
C	IN COLUMNS 5 THROUGH 80 OF THE FIRST CARD AND 5 THROUGH 64 OF
C	THE SECOND CARD, BUT WITH THE LAST 8 RESPONSES TO BE IGNORED,
C	THE FORMAT CARD SHOULD READ:
C		1-4,5-80/1-4,5-56
C
C     RELATED PROGRAMS
C	THE PROGRAM SORTER TABULATES THE RESPONSES TO EACH QUESTION OF
C	THE QUESTIONNAIRE BY FREQUENCIES AND PERCENTAGES.  THE PROGRAM
C	CROSS CORRELATES RESPONSES TO SELECTED QUESTIONS TO GIVE MAR-
C	GINAL FREQUENCIES, CROSS-TABULATIONS, AND OTHER STATISTICS AND
C	PERMITS THE COLLAPSING OF TABLES AND THE COMBINING OF VARIABLES.
C	THE PROGRAM MERGE COMBINES UP TO 64 FILES OF RESPONSES TO THE
C	SAME SET OF QUESTIONS.  THE PROGRAM UNITE COMBINES TWO FILES OF
C	RESPONSES TO DIFFERENT QUESTIONS BY THE SAME RESPONDENTS.
