Do you mean like that the data would disappear?

One example : the read-out after compilation of a module (picked at
random) with (*# data(const_in_code=>off) *) (and with shared_const off
too since
it is hard to calc sizes otherwise):

   Sizes = Code: 16885, Const: 3859, Data: 2627

which amounts to 23371 bytes.

With data(const_in_code=>on)

   Sizes = Code: 22849, Const:   11, Data: 2627

which amounts to 25487 bytes.

In this case, for some odd reason, not all the Const data goes away;
it normally gets to be 0. The total Size is also bigger which, I presume,
is because the data cannot be stored exactly the same way inside the code
segment (maybe on even 2 or 4-byte addresses, who knows). But a bigger
code segment won't hurt at all. The Data size is not affected.

This sample module contains an unusually big amount of data since it was
an old version from before I started to change things around for the
Windows one.

A look in the map file, after a full recompile/link of the real code,
revealed that a lot of space was freed in the DGROUP (but to no avail
since
Windows would not load the app).

Wait now! I may, with your help, have stumbled on something. From what I
can remember from the real code, I always get Const: 0 using the pragma.
Maybe (just maybe) if it does not get to be 0 there is a problem (shot in
the dark).

I will have to check tonight since the code is written on a computer not
placed at the department.

Bye
