[ 3 1 2 , 3 1 5 ] Fall 1980 This area contains the following new submissions: 1. DDT22.MAC - a version of DDT with a few bugs fixed and the addition of support for floating point numbers and instructions (provided you have a Floating Point Processor or the F.P. Emulator). This version will also run correctly on an LSI11 or under RT11 or both with reasonable operating system support. Floating point numbers may be entered or displayed in floating point and access to floating ACs and status is provided. Instructions are displayed, though opcodes had to be shortened because DDT was designed using a byte for text displacement... sorry 'bout that. 2. GREP - a version of RSX GREP enhanced from previous SIG tapes. The character "\" now matches space, or any of :;[]=/, so that matches may be made with strings including characters CSI will throw out. Also & is a totally wildcard character. There is a new switch /CO:nnn which will allow GREP to display the next nnn lines after a match also, though if it reaches a form feed it will stop even if its continuation count is not exhausted. 3. TPP - a Tape Position utility that will position tape, write endfiles, and read or write card image files to or from tape in ASCII or EBCDIC with block factors up to 100 card images. It can read tapes, in either code, with arbitrary record size (up to 180 bytes as assembled) onto a PDP11 file; it only writes card images. 4. LISTRS - the multicolumn lister revisited. Some minor improvements over the old versions, including the ability to really set page "length" to 1 line if the /NP switch to suppress pagination is used. Also the /ED switch takes a value to be used between pages if neither FF nor control D are desired. 5. MSX - A version of the MSX distributed operating system which updates the version on the Spring 1980 tapes. Some bug fixes and significant new functionality are suported. The version of MSX here has a conditional assembly code called SE$K which, if defined, includes code to handle multi-level security according to the DOD model. This code is not sufficient to give true MLS protection for the RSX environment, but the stand-alone version of MSX is probably secure provided that permanently resident tasks are really written secure and audited. 6. MCRDIS - This file is a corrector in SLP format to allow the RSX11M+ MCR dispatcher to throw out spaces and control characters that precede a legal command, and allow task names or CCL commands shorter than 3 characters. It also allowt the procedure Interpreter ...PIN to be called upon typin of #FILENAME to do an effective PIN FILENAME. This permits use of much of the software from the KMSKIT submission to the SIG tapes to make your RSX11M+ system more friendly. The corrections are inspired by the corrections done by Jim Downward to the 11M V3.2 MCRDIS. The file uses text locators as its sole means of positioning, so should work even after an autopatch.
