Astro,

   There are some incompatible concepts that you are unsuccessfully trying to make work together.

1.)  I do not think the [B]__RAM([/B][I]address[/I][B])[/B] alias knows how to formally handle strings.  The [B]__RAM([/B][I]address[/I][B])[/B] alias allows you to access to a [B]single[/b] byte of [B]RAM[/B].  I think you would need to assign each character independently being certain to increment the RAM address each time.  Also, most strings are terminated with a character value of zero to signify the end of the string.  So you would probably need to add a terminating value as well.

2.)  The [B]__READ([/B][I]address[/I][B])[/B] command used in your [B]SendStr[/B] subroutine reads data from [B]program memory[/B] not RAM.  So you can not use the [B]__READ([/B][I]address[/I][B])[/B] command to retrieve data stored in RAM.


   I think that if you use [B]SendChar __RAM([/B][I]address[/I][B])[/B] to send out data that is stored in RAM one byte at a time you can achieve the results desired.  If not, write back with what you tried and what happened.
