	MERGE
	-----

	THE FORTRAN PROGRAM MERGE IS INTENDED TO SUPPLEMENT THE PROGRAM
	SURVEY, ENABLING THE USER TO COMBINE SEVERAL DATA FILES INTO
	ONE.  RESPONDENTS TO A QUESTIONNAIRE MAY BE DIVIDED INTO SETS
	IN ANY CONVENIENT MANNER AND A SEPARATE DATA FILE CREATED FOR
	EACH SET.  THESE FILES MAY THEN BE MERGED INTO ONE LARGE FILE
	FOR SUBSEQUENT TABULATION OR ANALYSIS BY THE PROGRAMS SORTER
	AND CROSS.


      PROGRAM MERGE

      DESCRIPTION
	THIS PROGRAM COMBINES UP TO 64 FILES OF RESPONSES TO THE SAME
	QUESTIONS BY DIFFERENT RESPONDENTS.

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

      INSTRUCTIONS
	EACH SET OF CODED RESPONSES TO THE QUESTIONS SHOULD BE WRITTEN
	INTO AN ASCII DATA FILE BY THE PROGRAM SURVEY.  THE ORDER OF THE
	QUESTIONS SHOULD BE THE SAME IN EACH FILE, THOUGH IT IS PERMIS-
	SIBLE FOR SOME FILES TO HAVE EXTRA QUESTIONS AT THE END.

	THE PROGRAM WILL REQUEST THE NUMBER OF FILES TO BE MERGED AND
	THEIR NAMES.  THE NAME OF EACH FILE MAY BE ENTERED INDIVIDUALLY.
	ALTERNATIVELY, INSTEAD OF ENTERING A FILE NAME, THE USER MAY
	SIMPLY PRESS <RETURN>, IN WHICH CASE THE PROGRAM WILL ASSUME
	THAT SUCCEEDING FILES ARE NAMED "SET1", "SET2", ETC.  THE PRO-
	GRAM WILL ALSO ASK FOR THE NAME (NOT MORE THAN 5 CHARACTERS)
	THAT THE NEW DATA FILE IS TO HAVE AND FOR A DESCRIPTION OF THE
	SURVEY (NOT MORE THAN 48 CHARACTERS).
