Hi All, In line with my will to create an assembler, I started first by being able to execute something in memory, using the memory-mapper strategy. I am aware not all platforms use the same mechanism, but this is a starting point. At a later point, an inline assembler can be used by a (more abstract) JIT engine I put my repository here: https://github.com/santidhammo/guile-assembler Met vriendelijke groet, Sjoerd
