This compiler will choose some identifiers for desired address labels in the generated assembler source code. * Do you care which naming patterns can be applied there? * I observed that a renumbering of such labels can happen. This has got some “special effects” if you would like to compare small changes in source files from the other supported programming languages by a tool like "diff". Regards, Markus
