I have a program written in Fortran that runs on an IBM RS/6000
worstation. When I tried to compile it using g77 on RedHat 6.0 installed
on a Pentium III PC, I got an error msg because an string is assigned to
a variable without the explicit declaration of the CHARACTER type. Here
is the msg:

DATA BRANCO /'       '/
                             ^
Type disagreement between expressions at (?) and (^).

The variable BRANCO was not previously declared as CHARACTER. If I do
so, the compiler passes.
Since my program is composed of more than 500 subroutines and this
problem occurs on many of them, I am looking for a compiler directive
that allows this initialization. In the 'info g77', I found the
-fugly-init directive, but setting it produces no difference.
Could you please help me find out what is the correct directive or any
other way in which I can quickly solve this problem?

There is no compile time option to allow this, rather pre-historic
initialisation of REAL variables by CHARACTER data.

The best thing to do is to change the offending line(s) with:

DATA BRANCO /4H    /

(initialisation via "Hollerith strings" is allowed).

BTW, IBM probably really _loves_ your description of their machine
(a worstation ?) :-)
