This is a concordance or cross-reference utility for 'C' programs. This utility will operate on any file which ends in the suffix ".c". It will generate a new file with the original file name plus the suffix ".xref" which contains the cross referenced output from the utility. It will generate a list of all variable and function names in the source code, along with the line number in which they appear. In accordance with the operation of Think C‚Ñ¢, this program does not recognise nested comments, but it will properly deal with comments or quoted items which are inside single or double quotes.
