If installed, the command-line lexical comparator exists as a script file named Comparator.bat in the Run-time sub-directory of the Keywood installation directory.
To peform a lexical comparison of two COBOL files, type:
COMPARATOR.BAT <first COBOL filename> <second COBOL filename>
Each time the Comparator runs it appends information to a log file. The file is called Compare.log and it is placed in the \Temp subdirectory of your home directory, for example C:\Temp\Compare.log or H:\Temp\Compare.log.
