VERIFILE - Verify Contents of a File
------------------------------------

This program verifies the contents of a file. It may
be used prior to patching a file, for example.

Command Syntax -

     VERIFILE  fileid  </Quiet>

Notes -

     1. Verification data is read from the standard input
	device (usually redirected) until a blank line is
	read. Each line has the form:

	<+>offset  data<,data,...>  <* comments>

	Where "offset" is the starting byte offset in the file
	(a leading plus sign is optional) and "data" is an
	even number of hex digits supplying multiple bytes
	of data to be checked. For improved readability,
	commas may be inserted at any point (following an
	even number of hex digits).

	Lines beginning with an asterisk ("*") are considered
	to be comments and are ignored. Also, comments may
	follow the data on a line.

	As input is read, it is echoed to standard output.
	Use the "/QUIET" option to suppress this.

     3. Successful comparison results in a DOS return code
	of 0 and a nice message. A mismatch results in a DOS
	return code of 1 and a nasty message. Any other error
	returns a value of 2.
