Clear, thanks both. I've used something like that in the past when I needed a bunch of kbytes more to fit a program in memory.
But as I told debug strings are mostly mixed test+variables and become very difficult to manage this stuff, for example

Code:
Hserout2["logging ",DEC ByteCount," chars at @",HEX4 BaseAddress,"-Type ",HEX2 DataType,"-Data ",str inbuff\ByteCount*2,"-",HEX2 DataCrc,"                        "]
But some messages are all plain text, so I will consider to mix the two method

cheers
