The closest equivalent for macro processors is probably ML/I[0]. It’s implemented in macros[1]; you port it by defining macros that map it to a high level language or assembly language. William Waite’s Stage2[2], Robert Dewar’s Macro SPITBOL[3], and Macro SNOBOL4[4] are some other examples of systems implemented in macros.
