Just seeing if you were aweake. That's my story and I'm sticking to it. Some of the IBM internal use BSL documents were dated 1967.

PL.S, in the guise of BSL, goes back at least to the development of TSO and at least back to 1867. Some of the relevant manuals are ZZ, meaning IBM confidential, but some are GC, meaning publicly available, although still subject to copyright. -- Shmuel (Seymour J.)

There were dialects of PL/S for the 8100 (DPPX), and I think for the 37xx communication controllers. But in any case PL/S syntax is clearly based on that of PL/I, and that is certainly a highly portable language. It's also arguable that C is tied closely to the PDP11 and similar architectures, and only by ugly adaptations was it able to run on other platforms. > C also came out much earlier than PL/S, starting in about 1970. I don't think so. Both PL/S and C had predecessor languages that differed to various degrees. C had B and BCPL, from which C had very substantial differences. PL/S had BSL, which really wasn't much different from PL/S or even current PL/X (or whatever it's called these days). Both languages also have later dialects and/or offspring (e.g. PL.8, C++), and that history is complex. Wikipedia says that C dates from 1972. For PL/S it just says "the late 1960s", but there is BSL material on Bitsavers dated 1969, and a "BSL Library" document from October 1967 which is not BSL itself, but clearly refers to its existence. [Some of the PL/S documents on Bitsavers are the very same ones that had escaped to the wild and that IBM was chasing down around 1975. That they felt at the time that it was worth flying a team of blue-suited lawyers from Armonk around North America to try to get hold of fuzzy photocopies of BSL manuals does suggest that it was pretty important to them. I think this predated both the Fujitsu and Rand situations, but perhaps IBM was already aware of both efforts.] PL/eaSe: https://secure-web.cisco.com/1go2uHy-5yje8uqO2LaJUG-mISUqm2gS44XVUp-kQHA1pCD F5Bkst52bGgwQKgD4mN95xQfT-X-S56hVPNHD67rlt7PGyQCC6vzCK3LBs-usgUFcEOOcofsfAbP IAHyjgtl6cn3X2F1eL-KE__GhehAJvB6zcYx6cP2TYnRzTjBvQyDg1ch1eVXYzG2w52BW_SHXNyr m4P38kDkgFXZiWglXzhx8wlUIe_2rSfiyUjotiTRF9ZMdflYnUg0YmzYV3-qYVeoCp4LgbROUzGB wncwSJdyxf9HfO0JtLhPaAZhnxBzfYIvHo0ojdMeJzvpZmNJvFLVdeiI8nFI_MKtr4bJq-2WHJT9 vzgo2FJ20lQAP-6Uo2yAR__HoS9LiwiH8xi0B4O21KJxo5NieyRL-28K9Qtv8P_Jo4zfzxd0-8cy gj8pdRzYjRJd6NdE9TiJcX/https%3A%2F%2Fhttp://secure-web.cisco.com/1weAfPq5D-nQbPEDsOcDqtnGX_HPRp_aOyGtJVF7qvgSTHGuRKM6ezNKjTCA5FN9dNoZGj_GzKB8x6JOLtgRuTcyuhRSYg9y_HuojI2PnFRBmEFipAtC1MGR3QcQ0ktd7shtCYcV8RAcElvjSTjH3w9ATj4r1KqV9J0iIXbLz-klKMvQ7-gW8TZLuhcXcokd1Ax2SWXDqK477jS6wizWXxa6n1jZ4tEGthufTnE5Y4vC4fC5ImFOBm7q3I1Vj98QTgtNuGASTobpZBUUcDa2lD_eYfCBzfVI9Ef32yxY_xiQYy3OxKRXlhtYh7kVS6pQApzjTnvo5zn2Qb_1rx6CMlxS0yFO69BJ59i9W9zKkmwCa4cR5kLVdv_KH6xNAkaTrjwJJ9UEH6qT0XLZ-plHIUhKQAu6HJrz5_H46HrXXR4ALq8mlj3eKHSYo3OUU77xP/http%3A%2F%2Fwww.mxg.com%2Fthebuttonman%2Fhtml%2Fbut ton196.htm Rand's answer: https://secure-web.cisco.com/1y98GLznZFAPwsK3MR0lKo8vFRTlM-Vyfid72ddxIigrfdS ApIBAeRzJISYdjN0E5JPX_yrz9EkNrKoc-kgWXcBsJMrBWTUldhn4Dkq_mBIg1U8-VA4tmlh5V9A cVOtLIrKxDubfNnrAzV6lquQEb3G_7Gvw1IPcgQthcpt8AZVuL8c_kgY5XYN-VsEZyCKji_ZyCiU BxM2sq_vnQBywD4xw_wAv39d2fS3a-9uMijMVum6s-MzxTvp2pfQgi8ckDkV4atDiTUqTeHu8_wb zaZowyal5Umh-Wsmhmi4_-OaPQKMF2agA13nvl3UkPAyyrdnD9MWhoA7E9CcoNHMuYQP7n9Z7-OD wlnAKLB4_OuZMfYTep6Vz_-EsQnBOi9EpD1LVn_o7FY0hjyDnXR8OBv4F189ZIFZKZK504oXLbq2 35B-XAZTZSZoRxhwFToYPQ/https%3A%2F%2Fhttp://secure-web.cisco.com/1weAfPq5D-nQbPEDsOcDqtnGX_HPRp_aOyGtJVF7qvgSTHGuRKM6ezNKjTCA5FN9dNoZGj_GzKB8x6JOLtgRuTcyuhRSYg9y_HuojI2PnFRBmEFipAtC1MGR3QcQ0ktd7shtCYcV8RAcElvjSTjH3w9ATj4r1KqV9J0iIXbLz-klKMvQ7-gW8TZLuhcXcokd1Ax2SWXDqK477jS6wizWXxa6n1jZ4tEGthufTnE5Y4vC4fC5ImFOBm7q3I1Vj98QTgtNuGASTobpZBUUcDa2lD_eYfCBzfVI9Ef32yxY_xiQYy3OxKRXlhtYh7kVS6pQApzjTnvo5zn2Qb_1rx6CMlxS0yFO69BJ59i9W9zKkmwCa4cR5kLVdv_KH6xNAkaTrjwJJ9UEH6qT0XLZ-plHIUhKQAu6HJrz5_H46HrXXR4ALq8mlj3eKHSYo3OUU77xP/http%3A%2F%2Fwww.mxg.com%2Fthebuttonman%2Fhtml%2Fbut ton213.htm https://secure-web.cisco.com/1K1TClFFuiCkEmuQK1z77FgzwLRTvYxO0wJ30JFYi0Y3qSE V98cSJnn2mQCetCVpa65fjRV9o8c3QIjmkyFg0f68s-b1kBy38u6K6Y2c14ktZzc7qMkJrYFHy50 DVd2nyC3PjfcWJEgcGEUHeUQ9ZZv-H8LPfC0ID4JE-FnnTUg7imwEeqZHn25Uz1URUdJjtQa0pEV kADgB-v_JW385y2l6mmwMVHZfb8CN6W8nRdQHleI9leFZ3_Yd97p6MiEQ1f0ws37i1d2eBil_u1o OjpEMXgtQ8MdkoBpj-FmSO-S3S2xI_sffSn4T9mk5TgTOfO67yE51TWXBAzXrVw6MXjxST-fPAa4 a2S1_ThTtxUCsPaWIbEAU-HW3RN5Ut2f4npEzAeWefwa0tg9u4gl9JERLm5wMPBESTKLyym342db hkRJKtbfnaYIyD60b2kGlb/https%3A%2F%2Fhttp://secure-web.cisco.com/1weAfPq5D-nQbPEDsOcDqtnGX_HPRp_aOyGtJVF7qvgSTHGuRKM6ezNKjTCA5FN9dNoZGj_GzKB8x6JOLtgRuTcyuhRSYg9y_HuojI2PnFRBmEFipAtC1MGR3QcQ0ktd7shtCYcV8RAcElvjSTjH3w9ATj4r1KqV9J0iIXbLz-klKMvQ7-gW8TZLuhcXcokd1Ax2SWXDqK477jS6wizWXxa6n1jZ4tEGthufTnE5Y4vC4fC5ImFOBm7q3I1Vj98QTgtNuGASTobpZBUUcDa2lD_eYfCBzfVI9Ef32yxY_xiQYy3OxKRXlhtYh7kVS6pQApzjTnvo5zn2Qb_1rx6CMlxS0yFO69BJ59i9W9zKkmwCa4cR5kLVdv_KH6xNAkaTrjwJJ9UEH6qT0XLZ-plHIUhKQAu6HJrz5_H46HrXXR4ALq8mlj3eKHSYo3OUU77xP/http%3A%2F%2Fwww.mxg.com%2Fthebuttonman%2Fsearch.asp Tony H. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
