If you have too many options and files to fit on the command line, you can place them in a command file. Enter LGF command line arguments in a command file in exactly the same manner as on the command line. Command files may have as many lines as needed. Lines beginning with an initial # are comments.
To process a command file, preface the name of the file with the @ character. When LGF encounters a filename that begins with @ on the command line, it opens the file and processes the commands in it.
In this example, LGF reads its options from the file mycmds
Command files may be used both with other command-line options and other command files. Multiple command files are processed left to right in the order they are encountered.
