Nature of problem:
The ideal MHD equations are advanced in time. Given an MHD configuration, the result is the evolution of that configuration. The geometry is arectangular cylinder with conducting walls and periodic on the ends.

Solution method:
An explicit leap-frog time advancement scheme is used on a cartesian grid. The finite difference scheme is space and time centered.

Restrictions:
Only large scale instabilities can be well represented on the finite difference grid. The user should realize that large areas or parameter space have not been tested. Although the authors have run many cases which we believe are valid, we make no representation that results are valid for other than the case reported here.

Unusual features:
Heavy use is made of the IBM PL1 preprocessor.

Running time:
The running time is strongly dependent on the data. The case given in the test deck takes 22.24 min to compile, link edit, and execute on a 360/91.
