one of the guys is developing a fairly large program and has
been experiencing some problems.

- running a FORTRAN program with large data memory requirements > 5Mb ram


- what does the following error mean ?

  `` unable to unwind stack because of invalid stack frame 




       (process manager/process fault manager) ''

                                                     
- is there any specific limits on memory usage with fortran ?


- it was suggested that using the ``-save'' option with the compiler
  might help, in fact it seemed to make things WORSE!

any ideas?? suggestions??
thanks in advance
