Implement new default hand!er mechanism. Implement interim tape facility. Implement ''tape_arch.ive", COlillland. ow Doug Wells is.cleaning up his already existing comnand. Implement interim command metering tools. Change absentee to allow arbitrary nl.illber of args to be passed to absentee process. DC Debugging in progress. Command processor fixes. Debugging in progress. Implement changes which allow dynamic assignment of error codes. DPR Coding in progress. Change commands to use new cleanup proc mechanism. ST Design internal primitives which allow easier manipulation of multisegment files. DB Debugging in progress. Form revised 6/15/71

DPR Prepare SPS reference guide quality documentation of DTSS environment. PAK Final draft submitted. Change gate format, so that entry is through the text section. Inactive. Evaluation of cambridge Project area management subroutines. Final changes being made, Final documentation being prepared. Investigate what must be done to implement ''passive rings". Convert non-hardcore system to version 2 PL/I. CG Inactive version 2 ptl not ready. Fix backup dump and default error handler so they will conti~ue towork when default handlers are installed. CG Fix absentee so it will continue to work when default handlers are installed. Evaluate command metering proposal. Second draft in progress. Fl,, revised 6/15/71

Search system for compatibi~ity problems introduced by new access control. Docu- ment steps to be taken to minimize these. Form revised 6/15/71

6 GROUP FUNCTION TASK AREA Standard Service Task List New Object Segment Tasks DATE April 4, 1972 Code new tool object_irifo and change decode_object_ to call it. Change decode_definition_ to know about new format. Change pli and pbm to work with new format. Change binder to accept new format as input. Change translators (ALM, PL/I, FORTRAN) to generate new format. Change debug to work with new format (includes change to stu and writing of symbol block manipulation procedures.) Change default_error_handler_ to work with new format. Change binder to generate new format. Change all programs using old object segment tools to use new. (E.g., chan e linker to use ob ect info.) Change debug and default_error_handler_ to take advantage of additional infomation in new format. MJS MJS MJS MJS RM BLW DPR CG DPR CG START FINISH CHANGES/STATUS Works with old format. Needs to be debugged when some translator roduces new format. New subroutine being designed. At this point compilers which generate the new format can be installed. Slowed down. New person assigned to task must learn how binder works. Fozl revised 6/15/71 (

START FINISH CHANGES/STATUS Change programs that call object_info to know about new info. CB Learn structure of binder. Complete modifications to binder to accept new format as input. Form revised 6/15/71

Document reasons for needing a new inter-process connnunication mechanism. CHANGES/STATUS A_simplification of Spier's proposals, Document ideas for a new inter-process communication mechanism. Specify new system control structure. Specify the design of limited workspace asynchrony (needed for system control), Design overview of interfacing the file manager with the IO system. Design overview document complete. Fol revised 6/15/71 (._

10 GROUP FUNCTION TASK AREA Standard Seryice System Task List Good Ideas DATE April START FINISH CHANGES/STATUS Offline segments. Tape drive management. Includes reserving of drives. A disassembler to produce superdooper PL/I listings. Program to itemize all external references of a program or set of programs. Make commands with single arguments accept the equals convention. Improved error and question handler. Change quit mechanism to only allow certain commands to be typed after quit. e.g., "delete a. list = p,e,1 ". e.g., have "query codes", allow user to tailor response to particular error in particular command, Data base compiler. Expand help command to allow more selective printing of information, F~m revised 6/15/71
