SURVEY
	------

	THE FORTRAN PROGRAM SURVEY IS DESIGNED TO BE USED IN CONNECTION
	WITH THE PROGRAMS SORTER AND CROSS.  IT READS CODED OBSERVATIONS
	OR RESPONSES INTO A DATA FILE SO THAT THEY CAN BE TABULATED OR
	ANALYZED BY THE LATTER PROGRAMS.  WHILE IT IS EXPECTED THAT THE
	DATA WILL BE READ FROM CARDS, THIS IS NOT ABSOLUTELY NECESSARY.


      PROGRAM SURVEY

      DESCRIPTION
	THIS PROGRAM READS CODED RESPONSES TO A QUESTIONNAIRE AND WRITES
	THEM INTO AN ASCII DATA FILE.

      SOURCE
	NORMAN W. JOHNSON, DEPARTMENT OF MATHEMATICS, WHEATON COLLEGE,
	NORTON, MASS.

      INSTRUCTIONS
	THERE SHOULD BE NO MORE THAN 128 QUESTIONS.  RESPONSES MAY BE
	CODED BY ANY DIGIT FROM 0 TO 9.  ADDITIONAL SYMBOLS THAT MAY BE
	USED ARE THE MINUS SIGN (-), THE AMPERSAND (&), AND THE BLANK,
	INTERPRETED RESPECTIVELY AS THE NUMBERS 11, 12, AND 13.  THESE
	SHOULD BE RESERVED FOR SUCH CATEGORIES AS "NOT APPLICABLE",
	"DON'T KNOW", AND "NO RESPONSE".

	THE FIRST 5 COLUMNS OF EACH DATA CARD ARE FOR IDENTIFICATION,
	WITH THE FIRST 4 COLUMNS BEING UNIQUE TO THE RESPONDENT.  THE
	NEXT 67 COLUMNS OF THE CARD ARE FOR THE CODED RESPONSES, ONE
	COLUMN PER QUESTION.  THE LAST 8 COLUMNS ARE NOT USED.  IF THERE
	ARE MORE THAN 67 QUESTIONS, A SECOND CARD FOR EACH RESPONDENT
	MAY BE PREPARED IN THE SAME MANNER.

	THE SET OF DATA CARDS MUST BE PRECEDED BY FIVE OR SEVEN PROGRAM
	CARDS.  THE FIRST OF THESE HAS PUNCHED IN ITS FIRST 5 COLUMNS
	THE NAME THAT THE DATA FILE IS TO HAVE.  THE SECOND MAY BE USED
	FOR A DESCRIPTION OF THE SURVEY (NOT MORE THAN 48 CHARACTERS).
	THE THIRD CARD SPECIFIES THE NUMBER OF QUESTIONS (ANY FORMAT
	IS ACCEPTABLE).  THE LAST TWO CARDS OR PAIRS OF CARDS, PUNCHED
	IN THE SAME FORMAT AS THE DATA CARDS, INDICATE RESPECTIVELY THE
	LOWEST NUMBER AND THE HIGHEST NUMBER TO BE COUNTED AS A RESPONSE
	TO EACH QUESTION.  NUMBERS OUTSIDE THIS RANGE ARE TREATED AS "NO
	RESPONSE" AND EXCLUDED FROM THE TOTAL.  ON THESE CARDS BLANKS
	AND MINUS SIGNS ARE EQUIVALENT TO ZEROS, AND AMPERSANDS MAY NOT
	BE USED.

	THE LAST DATA CARD MUST BE FOLLOWED BY A SINGLE BLANK CARD OR A
	PAIR OF BLANK CARDS, ACCORDING AS ONE OR TWO CARDS ARE USED FOR
	EACH RESPONDENT.

	THIS PROGRAM ASSUMES THAT INPUT IS FROM THE USER TERMINAL AND
	OUTPUT IS TO THE DISK.  IF A DIFFERENT INPUT DEVICE, SUCH AS THE
	SYSTEM CARD READER, IS TO BE USED, IT SHOULD BE ASSIGNED LOGICAL
	UNIT 5 PRIOR TO RUNTIME.  ALSO, FOR INPUT FROM THE CARD READER,
	THE USER SHOULD RESPOND TO THE PROGRAM'S REQUEST FOR DATA BY
	TYPING "@CDR:".  FOR INPUT FROM A FILE ON THE DISK, THE USER
	SHOULD TYPE "@DSK:FILNAM.EXT", WHERE 'FILNAM.EXT' IS THE NAME
	OF A CARD-IMAGE SOURCE FILE.

      SPECIAL INSTRUCTIONS FOR NONSTANDARD SOURCE DECKS
	DATA CARDS DO NOT NEED TO BE PREPARED IN EXACT ACCORDANCE WITH
	THE ABOVE INSTRUCTIONS TO BE ACCEPTABLE, PROVIDED THAT (1) THERE
	ARE NO MORE THAN TWO CARDS PER RESPONDENT, (2) EACH CARD CON-
	TAINS AN IDENTIFICATION LABEL, AND (3) THE ONLY RESPONSE CODES
	USED ARE DIGITS, MINUS SIGNS, AMPERSANDS, AND BLANKS.  WHEN A
	NONSTANDARD SOURCE DECK IS INPUT, THE PROGRAM CARD SPECIFYING
	THE NUMBER OF QUESTIONS MUST BE REPLACED BY A FORMAT CARD GIVING
	THE BLOCKS OF COLUMNS IN WHICH IDENTIFICATION AND RESPONSES ARE
	PUNCHED ON EACH DATA CARD.

	FOR EXAMPLE, IF THE SOURCE DECK CONTAINS ONE CARD PER RESPONDENT
	WITH RESPONSES PUNCHED IN COLUMNS 1 THROUGH 72 AND IDENTIFICA-
	TION IN COLUMNS 74 THROUGH 80, THE FORMAT CARD SHOULD READ:
		74-80,1-72
	FOR A SOURCE DECK CONTAINING TWO CARDS PER RESPONDENT, HAVING
	IDENTIFICATION IN THE FIRST 4 COLUMNS OF EACH CARD AND RESPONSES
	IN COLUMNS 5 THROUGH 80 OF THE FIRST CARD AND 5 THROUGH 64 OF
	THE SECOND CARD, BUT WITH THE LAST 8 RESPONSES TO BE IGNORED,
	THE FORMAT CARD SHOULD READ:
		1-4,5-80/1-4,5-56

      RELATED PROGRAMS
	THE PROGRAM SORTER TABULATES THE RESPONSES TO EACH QUESTION OF
	THE QUESTIONNAIRE BY FREQUENCIES AND PERCENTAGES.  THE PROGRAM
	CROSS CORRELATES RESPONSES TO SELECTED QUESTIONS TO GIVE MAR-
	GINAL FREQUENCIES, CROSS-TABULATIONS, AND OTHER STATISTICS AND
	PERMITS THE COLLAPSING OF TABLES AND THE COMBINING OF VARIABLES.
	THE PROGRAM MERGE COMBINES UP TO 64 FILES OF RESPONSES TO THE
	SAME SET OF QUESTIONS.  THE PROGRAM UNITE COMBINES TWO FILES OF
	RESPONSES TO DIFFERENT QUESTIONS BY THE SAME RESPONDENTS.
