Hi, IMO, a description of how to modify is not a distribution of binary or source code. But should you decide to distribute a modified library (or object) then you must also distribute the modified source. Btw. Are you aware that you don't need to modify z80.lib to use a different putchar? Just compile and link your modified object and sdld will not search for it in the lib.
