To run this on MVS, you need a JCL job card deck, to define the batch job to the system. Here's a version that is designed to run interactively. I'm using this JCL, because the program in "monitor" mode is designed to self-terminate after 5000 iterations of a loop. This "interactive" version will produce the complete set of output.

Mainframe batch jobs are designed from the start to produce printed output. They were written in an era where end-user applications presented interactively on a screen were not really an option. The only people who had screens were engineers, system operators, and programmers. Everyone else interacted with computers by way of printed output. To see the output from this program, you can [download it here](http://gmgauthier.us-east-1.linodeobjects.com/docs/mymort1.pdf).
