watch module variables in CVF66c

Does anyone know how we can watch private variables owned by a module?
i.e.

module XYZ

implicit none
REAL(8), ALLOCATABLE, private :: a(:),b(:,:,:),c(:,:,:)

contains
.....

I put the names a,b,c in the watch window but I get a message of "undefined
variable"..

try XYZ::a instead.

Nice tip. Do you know how to watch parameters, too?

There might (I don't know for the particular compiler) be some compiler
option to force otherwise, but realize that in general, parameters don't
even exist at run-time, so there isn't anything to watch. A parameter is
fundamentally a compile-time thing; it doesn't in general have a
run-time address or anything.

(I assume you are talking about parameters as in those things defined by
parameter statements - what the Fortran standard calls named constants.
If you are talking about dummy arguments, that's different. I mention
this only because the terminology in other languages is different and it
is not unheard of for people to say "parameter" when they mean an
argument in Fortran).

Thanks, Richard. I speak of named constants. Sometimes I want to know
what they are for debugging purposes. I end up writing a one-line
function that returns them and once everything is working I delete the
functions. Because it's for debugging only, it would be nicer to have
a "watch window" way to do this. Thanks again,

i don't think you can (or i haven't found out how to do it).

CVF does not support evaluation of PARAMETER constants in the debugger. The
:: syntax for viewing module variables is documented in the CVF Programmer's
Guide chapter on using the debugger.
