Hi
I am debugging fortran code and I want to see if an interior value is
equal to .FALSE.
I know how to get the value with parse_and_eval but what do I do with it?

Can we assume this value is an integer?
Then you should be able to do something like this:
long foo = value_as_long (parse_and_eval (my_value));
if (foo == 0)
[...];

no. it's a logical. Either .TRUE. or .FALSE.

GDB values in Python scripts can be directly compared with Python's
native types, so you can just say:
foo = gdb.parse_and_eval ("foo")
if foo == True:
print 'hooray'

That's a bit redundant, just as it would be in C. I would write:
foo = gdb.parse_and_eval ("foo")
if foo:
print 'hooray'

In addition to what Thiago said, if the documentation (specifically the
node "Values From Inferior") is unclear, we'd appreciate comments on how
to improve it.
