C vs. Fortran speed:  Since C variables are automatic (i.e., dynamic) by
default and Fortran variables are static, is it fair to conclude that in
general, a routine in C having the same number of local variables as
a "roughly identical" Fortarn routine will take a bit longer because
the OS must allocate (and deallocate) space for the local variables?
If the C local variables are made static, does this possible performance
advantage disappear?

In Fortran, it is sometimes convenient to use the END=n, where n is a label
number, in a READ statement to transfer control when an EOF is detected.
Has anyone found a *simple* way to get the same effect in C?  I had been
fopen on TT:, then using a while (!feof(fptr)) {...}, but this still results
in the loop body getting executed unless yet another foef() is put within the
loop to "double" check for EOF.

Thanks for any help or suggestions.
