Old Fortran Program

Steve:

I came across an old Fortran program from UCLA.  It is a very useful program and the site provides a copy of the program complied in Compaq Fortran in 32 bit.

I tried unsuccessfully yesterday to compile the program.  I broke it down into reasonable units and slowly worked to fix some things.

But when I get to the FEM module - it starts and never stops on the compiler.  I stepped through it by adding back a line at time, but could not spot the error.  If I did not have a working EXE I would wonder, but there is a working exe in Windows.

Any ideas, I enclose the original code and the modifications I made. It is an interesting program that has the potential to save lives in earthquakes so I am keen to get it working.  If I cannot I will rewrite the algorithms in C#.
