I've broken my code - running out of hair - please spot the obvious mistake

pacman

I managed to break my code (it's a skill I have).

Basically I'm reading a string of serial data and doing stuff with it...

Towards the end of MAIN I call a debugging routine called PrintBuffer, then I call the CheckMessage routine. The very first step of CheckMessage is to call PrintBuffer again as somewhere beteen the printBuffer calls it gets screwey.

so in Psudeo code

Main
...
PrintBuffer(@InBuffer)
CheckMessage (@InBuffer)



CheckMessage (message)
PrintBuffer (@message)



How can the two strings from PrintBuffer be different?

Huge thanks in advance

message is an address so there is no point in dereferencing it again. IOW get rid of the @.

THANKS Kuroneko.

Seems just when I _think_ i've got a handle on string data - I make a mistake like this...

FWIW, if you ever use byte MBStack[100] (currently unused) for cognew please make it a long array first.
