The command line is:
run dfconv profile-fname [input-fname] [output-fname] [-d]
The input and output file-names are optional as they can be extracted from the profile file. If you specify file-names on the command line as well as in the profile file, those on the command line take precedence.
After conversion, the operating system error level (ERRORLEVEL) is set to non-zero if an error occurred during conversion. If you are running the conversion from a batch file, you can interrogate this to determine what action to take after the conversion.
