You can pass arguments to a main program on the command line. The operating system calls main programs with a string that contains the arguments.
How the arguments are treated depends on whether you use the -host option of the cob2 command.
If you do not specify the -host option, command-line arguments are passed in native data format.
If you specify the -host option, Windows calls all main programs with an EBCDIC string that contains the command-line arguments. The length of the string is in big-endian format.
