Trouble with a fortran loop and getting it into mathcad

[msu12181]

Hi guys

I have to admit upfront I am new when it comes to programming. I am having trouble getting the following fortran do loop converted over into mathcad. It looks like the program is running through and getting initial results and then taking those to use for the next iteration and so forth...like a cumulative sum. Seems like it shouldn't be all that hard but I can't get things to initiate correctly. Can anybody get me back on track?

Thanks

See if the attached fulfills your needs.

Should mention that I didn't check the formulas.
