With arrays that size you are going to run into additional problems due to bank size (96) on the 16F series chips. You will either have to work around the bank size problem (there are lots of posts in this forum about the subject) or you might want to look at using the drop in replacement 18F series that eliminates the bank problem.

Many many thanks to you for your good explanation. I could not find that explanation in the CCS_Manual.pdf. It must be there. I am looking here 2 times.
Thanks a lot

First comment. You can make your const arrays work, by adding the
instruction:

#device PASS_STRINGS=IN_RAM

Just after the processor include line.

Understanding this is a key feature of the PIC. Unlike 99% of other
processors, the PIC has the ROM as a completely separate memory space
to the RAM. So there are two address '0's, one in ROM and one in RAM.
A 'pointer', is inherently a RAM address, so const arrays won't work with
'pointers'.

The PASS_STRINGS option tells the compiler to create 'virtual' pointers
to strings stored as const's.

Then the ?: syntax, normally requires the test parameter to be in
brackets. Depending on the line being used, this is _required_ to make
the parsing work. Forcing this to be evaluated before the next statements.

((i < 16) ? codes0[i] : codes1[i - 16])

I'd probably also bracket the whole entity as well to ensure that the
printf sees it as a single value.

However 'PASS_STRINGS' requires a reasonably recent compiler.
