A pointer and bit are returned. 25* 26* 27* 28* HISTORY: 29* 30* 77-07-01 J. A. Weeldreyer: Initially written. 31* 32* 80-01-09 Rickie E. Brinegar: to accept a descriptor pointer rather than an 33* assign_ descriptor type, and eliminate the need of a length parameter. 34* 35* 81-02-24 Rickie E. Brinegar: the set entry point was removed. Both 36* linus_set and linus_assign_values (the only two modules that referenced that 37* entry point) were modified to do their own allocation and freeing. 38* 39* 81-11-06 Rickie E. Brinegar: Removed unreferenced mod builtin function. 40* 41**/ 42 1 1 /* BEGIN INCLUDE FILE linus_lcb.incl.pl1 -- jaw 8/30/77 */ 1 2 1 3 1 4 1 5 /****^ HISTORY COMMENTS: 1 6* 1) change(86-04-23,Dupuis), approve(86-05-23,MCR7188), audit(86-07-23,GWMay), 1 7* install(86-07-29,MR12.0-1106): 1 8* Added general_work_area_ptr and renamed sfr_ptr to 1 9* force_retrieve_scope_ptr. 1 10* END HISTORY COMMENTS */ 1 11 1 12 1 13 /* HISTORY: 1 14* 1 15* 78-09-29 J. C. C. Jagernauth: Modified for MR7.0. 1 16* 1 17* 81-05-11 Rickie E. Brinegar: added security bit and andministrator bit as 1 18* a part of the attribute level control work. 1 19* 1 20* 81-06-17 Rickie E. Brinegar: deleted the sd_ptr as a part of removing the 1 21* scope_data structure from LINUS. LINUS now depends totally on MRDS for 1 22* scope information. 1 23* 1 24* 81-11-11 Rickie E. Brinegar: added the timing bit and three fields for 1 25* retaining various vcpu times to be collected when in timing mode. The 1 26* times to be collected are: LINUS parsing time, LINUS processing time, and 1 27* MRDS processing time. 1 28* 1 29* 82-01-15 DJ Schimke: Added the build_increment and build_start fields as 1 30* part of the line numbering implementation. This allows for possible later 1 31* LINUS control of the build defaults. 1 32* 1 33* 82-03-01 Paul W. Benjamin: Removed linus_prompt_chars_ptr, as that 1 34* information is now retained by ssu_. Removed parse_timer as no longer 1 35* meaningful. Added linus_version. Added iteration bit. Added 6 entry 1 36* variables for ssu_ replaceable procedures. Added actual_input_iocbp. 1 37* 1 38* 82-06-23 Al Dupuis: Added subsystem_control_info_ptr, 1 39* subsystem_invocation_level, and selection_expression_identifier. 1 40* 1 41* 82-08-26 DJ Schimke: Added report_control_info_ptr, and 1 42* table_control_info_ptr. 1 43* 1 44* 82-10-19 DJ Schimke: Added ssu_abort_line. 1 45* 1 46* 83-06-06 Bert Moberg: Added print_search_order (pso) and no_optimize (no_ot) 1 47* 1 48* 83-04-07 DJ Schimke: Added temp_seg_info_ptr. 1 49* 1 50* 83-08-26 Al Dupuis: Added query_temp_segment_ptr. 1 51**/ 1 52 1 53 dcl 1 lcb aligned based (lcb_ptr), /* LINUS control block */ 1 54 2 db_index fixed bin (35), /* index of open data base, or 0 */ 1 55 2 rb_len fixed bin (21), /* length of request buffer */ 1 56 2 lila_count fixed bin (35), /* number of LILA text lines */ 1 57 2 lila_chars fixed bin (35), /* number of LILA source test chars */ 1 58 2 trans_id fixed bin (35), /* used by checkpoint and rollback facilities (MR7.0) */ 1 59 2 lila_fn char (32) unal, /* entry name of lila data file */ 1 60 2 prompt_flag bit (1) unal, /* on if in prompt mode */ 1 61 2 test_flag bit (1) unal, /* on if in test mode */ 1 62 2 new_version bit (1) unal init (1), /* on for new version data base (MR7.0) */ 1 63 2 secured_db bit (1) unal, /* on if the db is in a secure state */ 1 64 2 administrator bit (1) unal, /* on if the user is a db administrator */ 1 65 2 timing_mode bit (1) unal, /* on if timing is to be done */ 1 66 2 iteration bit (1) unal, /* interpret parens as iteration sets */ 1 67 2 pso_flag bit (1) unal, /* add print_search_order to select */ 1 68 2 no_ot_flag bit (1) unal, /* add no_optimize to select */ 1 69 2 reserved bit (27) unal, 1 70 2 liocb_ptr ptr, /* iocb ptr for lila file */ 1 71 2 rb_ptr ptr, /* ptr to request buffer */ 1 72 2 is_ptr ptr, /* iocb ptr for currentinput stream switch */ 1 73 2 cal_ptr ptr, /* ptr to current arg list for invoke (or null) */ 1 74 2 ttn_ptr ptr, /* pointer to table info structure */ 1 75 2 force_retrieve_scope_info_ptr ptr, /* structure pointer to force retrieve scope operation */ 1 76 2 lv_ptr ptr, /* pointer linus variables */ 1 77 2 si_ptr ptr, /* pointer to select_info structure */ 1 78 2 setfi_ptr ptr, /* pointer to set function information */ 1 79 2 sclfi_ptr ptr, /* pointer to user declared scalar fun. names */ 1 80 2 ivs_ptr ptr, /* pointer to stack of invoke iocb pointers */ 1 81 2 lit_ptr ptr, /* pointer to literal pool */ 1 82 2 lvv_ptr ptr, /* pointer to linus variable alloc. pool */ 1 83 2 rd_ptr ptr, /* point to readied files mode information (MR7.0) */ 1 84 2 rt_ptr ptr, /* point to table of relation names and their readied modes 1 85* (MR7.0) */ 1 86 2 actual_input_iocbp ptr, /* ptr to input while in macros */ 1 87 2 lila_promp_chars_ptr ptr, /* pointer to the prompt characters for lila */ 1 88 2 linus_area_ptr ptr, /* LINUS temporary segment pointer */ 1 89 2 lila_area_ptr ptr, /* LILA temporary segment pointer */ 1 90 2 i_o_area_ptr ptr, /* temporary segment pointer used by write, print, create_list */ 1 91 2 rel_array_ptr ptr, /* ptr to array of names rslt info structure 1 92* for current lila expression */ 1 93 2 unused_timer float bin (63), /* future expansion */ 1 94 2 request_time float bin (63), /* How much request time was spent 1 95* in LINUS.

This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology, Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell BULL Inc., Groupe BULL and BULL HN Information Systems Inc. to the development of this operating system. Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970), renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture for managing computer hardware properly and for executing programs. Many subsequent operating systems incorporated Multics principles. Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc., as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. . ----------------------------------------------------------- Permission to use, copy, modify, and distribute these programs and their documentation for any purpose and without fee is hereby granted,provided that the below copyright notice and historical background appear in all copies and that both the copyright notice and historical background and this permission notice appear in supporting documentation, and that the names of MIT, HIS, BULL or BULL HN not be used in advertising or publicity pertaining to distribution of the programs without specific prior written permission.
