The obvious difference is that C/C++ etc are still evolving. The C23 and C++23 standards are due for ratification next year. C++ from 1998 is a different language to C++20. PL/I has been functionally stabilised for decades. The z/OS COBOL compiler hasn’t implemented significant features of the ANSI standard. If I were a COBOL programmer I would like the language to support collections, dictionaries etc but I suppose the type of applications where COBOL is used don’t require hash tables. > > -- > Shmuel (Seymour J.)
