Hello,
I have a gigantic data table stored in Flash memory on a PIC16F1936:-
greater than 3K words arranged as a series of dt statements. I'm using
the INDFn registers and MOVIW instructions to access the data so it
doesn't really matter where it is placed for it to still work.

When I link together the various relocatable modules in my code some end
up before and some after the data table.

The problem is that I have to use PAGESEL to jump to those bits of code
after the table. I know that all of my code will fit in the first page,
and speed is important in this application, so I would rather avoid
PAGESEL altogether and have all the executable code in the first page and
lump the table anywhere on the end.

For fairly obvious reasons I would rather not specify exactly where every
module resides in memory but still some how force the linker to place the
table afterwards.

I have tried to specify where to place the table by absolutely
positioning it in memory:

TABLE_SECTION	CODE	0x800

BIGTABLE	dt	0x00, 0x01, 0x00, 0x02
		dt	0x01, 0x31, 0x00, 0x42

etc...

However this doesn't change the link order--it still puts the same code
modules after the table (just shifted even further up the Flash)

Am I missing something obvious or is there really no way around this issue?

I'm using "MPASMWIN.exe v5.35, mplink.exe v4.35" with MPLAB v8.43 and the
standard linker file.

Thank you very much if you can help.
