You may emulate multiple entry points into an SPL program by using the
argc, argv, parm, and info parameters of the HP C/XL main function, and
coding a switch statement to goto the appropriate labels. (See "SWITCH
Declaration" above for the format.) In HP C/XL, you may pass arguments
to these parameters with the INFO= and PARM= parameters of the MPE XL
:RUN command.
