How to use and modify a public member data which was declared in another fix command class by using pointers?

Please keep the list in the loop.

This is a basic C++ issue. You've added an array
to a specific fix class of your own. You can't access
it thru a generic fix pointer, since Fix.h doesn't know about
it. Your have to cast the generic pointer to one to your class.
Something like:

double **efg = (FixABCD * fix[i])->efg;

Please keep the list in the loop.

FYI, with most e-mail programs, you need to click on
"Reply to all" instead of "Reply" to make sure that a
copy is sent to the list. otherwise you can add
the email address of the list in the cc: field.

this way the entire conversation is archived in
the mailing list archives and somebody that has
similar problems as you can research them in
the archives and thus everybody benefits.

thanks,
