How do you add text so that appears is the s19 file.

I want to add software name / author in some code so that if you read back the device you can read the text.

I want to do this in the ST7 assembler

You may do that directly in the window of the visual programmer, where the memory is free of any code. Or maybe by adding a constant declaration in your code.....

If I want to set up a constant how do you define a string in assembler.

DS.B is a byte

DS.W is a word ?

in your map file (for example):

SEGMENT BYTE AT F000-FF00 'ROM'

SEGMENT BYTE AT FF00-FFDF 'TITLE'

in your source file

SEGMENT 'TITLE'

DC.B 'A'

DC.B 'B'

DC.B 'C'

the string ABC will then be located starting from adress 0xff00 (check it in the window of the visual programmer)

why not just use the STRING keyword, eg.

segment 'rom'

STRING ''teststring''

because I forgot this possibility

Anyway, you still have to define the segment if you want to allocate it at a defined adress.

How can I do this in C (Cosmic C-Compiler)?

I mean to add software name / author in code.

define a new section in your linker file,eg.

+seg .str -b 0xf000 -n .str # special const section

+seg .text -n .text -a .str # program code

+seg .const -a .text # constants follow code

then to put our string in the special section use

#pragma section const {str}

const char * const pString = ''teststring'';

#pragma section const {}

Hope this helps
