I have a very large fortran program.Many
variables are not inialized at the start of
the program.HP & IBM fortran in unix assume
that undeclared variables are zero.
Is there a flag I can set do overcome the
problem in Linux.

Thanking You

the option -finit-local-zero solved one
problem but did not solve the below:
a subroutine that is called many times had
the undecaled variable set to zero on each
entry to the subroutine instead of entering
with the last value it had on return from
the subroutine.
what is needed is a once only zero initialization.
Can you help ??
Thank You

If you are talking about SAVEing across procedure calls, you could try the flag

-fno-automatic
