As much as I hate C enemies, I must admit they were for some reason better at standard. If Pascals were such religiously adopting the standard and if C was remaining as fragmented as Pascal, with "otherwise" in one dialect and "else" in another one, then Pascal could win. Probably not the Turbo Pascal as we know it. Another Pascal, standard enough Pascal.
Or maybe it should have been Modula-2. Amiga had TDI Modula-2. Don't know if TopSpeed Modula-2 and TDI Modula-2 were source compatible, but I guess far more than different Pascals.
This table is built by ex. Pascal developer that moved to Ada: https://p2ada.sourceforge.net/pascada.htm
Indeed, Ada's standard conformance is a breathe of fresh air.
But Amiga had no Ada compiler, and had Modula-2 compiler. So for the sake of good guys' winning, if time machine moves me to 80s, I would pick Modula-2 for every platform. Nowadays Ada is a choice of good guy
