>So no ISVs? Or they code at the MI level. Sorry. There are ISVs. But only for application level code, not "system" level. IBM supplies compilers for COBOL, RPG, CL (similar to CLIST), C/C++, Java, and maybe other languages. But you cannot create a compiler because the interface to create an MI level program does not exist (no assembler). You could write a interpreter in C/C++, I guess. But that would slow down the language. > >But I could draw a parallel to z: > > SLIC == microcode, millicode Right. Remember all the "microcode assists" for the various OSes on various models of the S/370? The AS/400 is like that, but even more so. A great deal of the OS (including the database) is embedded in the SLIC. > MI == assembler for z. Right. Except no HLASM-like language and so no way to program in assembler (at the MI level). > <snip> >-- gil > >---------------------------------------------------------------------- >For IBM-MAIN subscribe / signoff / archive access instructions, >send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO >Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
