This partitioned file contains all the source required to make up a version 26C Supervisor, plus the version of the IMP compiler and FIX utility used at Edinburgh to do so. This compiler is necessary as some advanced language features are required which are not available in the service compiler. Note that the OPTION NOBRACKETS must be in force in the process being used for the method described to work. Two "OBEY" subfiles are available: MAKECHKD and MAKEOPT. They each construct a test Supervisor which is left in file SUP26xT, where x is 'C' or 'O' respectively. Making a Supervisor thus consists of the following: a) INSERT the IMP compiler and FIX utility into the current directory (and then log off and log on again if IMP was previously used in this interactive session): Command:INSERT SUP26CSRCE_NRIMP09Y Command:INSERT SUP26CSRCE_FIX10Y b) Set up the steering file CTOPT in the process. This file contains the conditional compilation options which enable the Supervisor to be tailored to Site requirements. A sample subfile "SAMPLECTOPT" is included as an illustration. This file is one used at Edinburgh to construct the 2970 Service Supervisor. The options available are intended to be self explanatory; any restrictions or limits are included in "SAMPLECTOPT" as comments.(NB the version of CTOPT used for the previous release will not work. The options have been re-arranged and extended!) Command:EDIT SUP26CSRCE_SAMPLECTOPT,CTOPT E c) OBEY the selected subfile; e.g. Command:OBEY SUP26CSRCE_MAKEOPT Two unused procedures are normally flagged by the FIX utility. d) Use command PRG, (requires OPTION SEARCHDIR=ENGINR.SYSLIB) to put the test Supervisor onto a disc for loading. (Your process must be privileged: ACR<=5, to use PRG.) For example: Command:PRG SUP26CT,disclabel,site Sites on the system discs will have been allocated for this purpose. "disclabel" must be a 6-character label, e.g. EMAS02. "site" must be specified as a hex number, e.g. X180. Two versions of GPC are contained in this partitioned file. They are identicle except for the GPC microprograms included therein. GPC28S has the well tried version C01 microprogram, GPC29S has the new imporoved C03 microprogram which has caused problems on one of the GPCs in Edinburgh. Take your pick!!!
