But, from what little I know, most of the new stuff is written in PL/S or whatever. It doesn't do much good to have source when you don't have a compiler! Part of the "lock down" occurred when IBM transitioned from a "pure" hardware company (where software was only used to help sell hardware) to a hardware + software company where software in itself became a source of income. And the OEM CPU people may have been a part of it too since they used IBM software (like OS/MVT) without the need for a license (due to IBM overlooking copyrighting the OS). Another part of OCO is to keep information away from users so that they don't use non-GUPI interfaces in such a way as to force IBM to "freeze" that interface due to its popularity. -- John ---------------------------------------------------------------------- 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
