<http://gcc.gnu.org/fortran/> says "We highly encourage users to move 
from g77, which is no longer maintained, and start taking advantage 
of GFortran's modern features. Legacy g77 code will compile fine in 
almost all cases."  But instead of messing around wasting our time 
trying to write Fortran, why don't you try Python?

Anyhow, "begin program" looks wrong -- I don't remember 'begin'
as a Fortran keyword -- and I think F77 doesn't support free-form
input, only fixed-form.  <http://gcc.gnu.org/wiki/GFortran#manuals>
has some manuals I plan to not look at, but you could do so.

Note, <http://gcc.gnu.org/wiki/GFortranUsage> says, ""Fortran 95 
allows for [free form and fixed form] ... The rule in place is 
as follows:     1.  Files whose name ends in .f or .for are assumed 
to be fixed form     2.  Files whose name end in .f90 or .f95 are 
assumed to to be free form   3. For other files [use] command line 
options..."  

If you post again about this problem, make sure you cut and paste
the exact code you are compiling; show the command you used for 
the compile; and show the compiler's output instead of the useless
remark "doesn't seem to work".
