Well, there were two different problems:

1) My intrinsic lack of Fortran know-how

2) The fortran code failed to translate when it turned out that
Fortran could change the type of a matrix multiplication depending on
the dimensions of the two input matrices.
Sometimes the output was a simple vector and sometimes a true 2-d
matrix and I failed to undretand how to translate these functions.
It seemed like Fortran didn't give a damn about variable types and
since Pascal is so strongly typed this made a big clash.

I converted a fair amount of them but when I reached this problem I
had a lot to go and gave up.....
