An output file is created with the same name as the input file except with the extension changed to .fmt. The format may be changed by using qualifiers on the command line or in an optional startup option file. The startup option file is placed in the user's home directory and named .iccfmt. The startup option file can contain any options that may be specified on the command line. Ada-style comments are also supported.
Error recovery is minimal.
If any errors should occur while parsing the input source file, NO .fmt file is generated and at least one error message indicating the filename, line number of the first detected error, and type of the error is printed to standard output. Specifies the output file name. By default, the output is written to a file in the current working directory with same name and an extension of .fmt. This qualifier may not be specified when formatting multiple Ada source files. The default is column 40.
