	This is the user's guide for the MATCHB program.  This guide gives
step-by-step instructions and useful hints for operating MATCHB.  The format is 
is to print, in the order in which they might appear, the system prompts to
the user and then list what the responses might mean.

	To start an installed MATCHB program from monitor mode, the user would
simply type:
          
                               RUN MATCHB

	The system prompts will appear in all capital letters, while comments
will be in lower case:

 1.  ENTER NAME OF FIRST INPUT FILE

	This requests the name of one of the in put files.  Simply type out the
	name of the file in the form:  DEV:FILENAME.EXT.  The syntax is checked
	by the system as it tries to open a file.  Therefore, a system error
	will occur if a bad specification is made.

 2.  RECORD SIZE?

	This requests the maximum number of characters any record in the file
	is expected to have.  Any record size from 1 to 51 will be accepted
	by MATCHB.  Record sizes above 51, however, will result in an error.

 3.  STARTING POSITION OF KEY?

	This requests the character position of the first character in the key
	of each record in the file.

 4.  ERROR MESSAGE FOR NO MATCH FOR 1ST FILE RECORDS ON OTHER FILE?

	This requests the user to enter an error message stating that a 
	record from the 1st file was read that does not contain a matching
	record on the 2nd file.  The error message and the record in error
	are both written to the Error Output File.

 5.  ENTER THE NAME OF THE SECOND INPUT FILE

	This requests the name of the other input file to be compared in
	MATCHB.  The rules that apply to the entry for the first input file
	also apply this entry.
