Instructionsfor compiling the programs on the 32016appear in the 32016 section. 105 - About this Issue 106 - Presenting Programs Part 3 of the series of articles bySteven Flintham (15A) explains how tocreate a 3D-effect in screens.

Option 999 will take you to the Issue24 software menu. Note that thesoftware menu also has an option todisplay any messages sent to youpersonally. The software available is as follows: Games & demos etc. Patience An excellent-quality rendition of thepopular game by Carl Wheat (204).Instructions are included, andadditional details are in the "ProgramDocumentation" section of the magazine.Intellectual Hangman A challenging version of Hangman forthose who know lots of long words,written by James Cavanagh (1V5). Christmas Cracker An amusing program with skilful use ofsound and Teletext graphics, written byRoy Dickens (20G). 12 Days of Xmas A rather alcohol-orientated variant onthe original, with words and music byJames Cavanagh (1V5). Graph14 Miroslaw Bobrowski (L1J) has suppliedthis impressive 3D graphical program byPiotr Sliwinski, a 14-year-old Polishschoolboy. The program produces3-dimensional landscape-type graphs offunctions such as Z=f(X,Y), andMiroslaw has also added a number ofsample functions to producedemonstration landscapes. Despite beingwritten on the Acorn Electron, theprogram runs on the BBC B and Master,and is also TUBE-compatible, producinga much faster picture with a differentbackground. 3D Screen Demo The demonstration program for StevenFlitham's article on producing a 3Dstyle of screen display. 3D Screen Demo (B) A crunched version of the demo,allowing it to run on BBC 'B's that areshort of memory. Towers of Hanoi A ready-compiled version of the Small-Cprogram by A.J. Travis, included toshow the flexibility and speed of 8-bitSmall C. Note that NONE of the Small-Cprograms are TUBE compatible. N.B. this program *** only *** appearson the ADFS version of Issue 24 Applications Bank Manager A program written by Piotr Pagowski tohandle just about any type of financialproblem, and sent in by MiroslawBobrowski (L1J). Full instructionsappear in the "Program Documentation"article. Disk Envelope Creator An excellent utility by AndrewSnodgrass (YJ2), which prints out diskenvelopes onto paper, including flapsto allow you to stick them together. Fahrenheit to Celsius A ready-to-run version of Dr.A.J.Travis' Small-C program. The sourcecode for the program appears in thedisk magazine. The program produces alist of temperatures, with Fahrenheiton the left, and Centigrade on theright. Form Master Another copy of the program featured inIssue 22; this time I have rememberedto put the instructions in. Sim City Cheat Andrew Snodgrass (YJ2) has suppliedthis program which allows you to altersaved Sim City files. Picture Gallery V2 An improved version of the program written by Paul Walden (24K) to displayscreen files. Utilities Econet Tree This program, by J.G. Harston (W79) ofHarston PD, is an excellent way ofdisplaying ADFS, HADFS, NFS or ANFSdirectory stuctures. RAMdisk A useful utility for machines withsideways RAM, contributed by JohnIlsley (27N); I don't think I've seenone like it anywhere else. Simply use*RSAVE <filename> to transfer a filefrom memory to sideways RAM, and *RLOAD<filename> to retrieve it. More thanone file can be stored in SRAM at atime. Use *RCAT to list the filesstored, and *RDELETE to remove any ofthem. Multiple Access This program, again sent in by JohnIlsley, asks for a list of filenames,terminated by pressing RETURN withoutentering a filename, and then does*ACCESS WRL commands on all the filesnamed. NB currently ADFS only. Bulk Delete This program is similar to the oneabove, but accesses and deletes all thenamed files. It is NOT recommended thatyou try this out before making a backupof your issue disk. Number Rounding This program, erm, rounds numbers. DFS Recover The last of the programs contributed byJohn Ilsley, this one can be used torecover data from DFS disks. File Compare Another program written in Small C. Itcan be used to compare two similarfiles byte-by-byte, and produces alisting of all the bytes which aredifferent. As well as being run fromthe 8BS menu, the program can be usedas a * command on its own, with thesyntax *cmp <file1> <file2>. OTHER SOFTWARE Included in the software section of thedisk are the files TINY, TABLE andITALICS. These are the machine-codeprinter utilities described in article115, and should be run by *<filename>. In directory :0.S on the DFS version,and $.ReptnScrns on the ADFS version,there are the four sets of Reptonscreens for the competition. Theyshould be loaded into Repton in theusual way. ARCHIVED SOFTWARE There is only one archive on thisissue,in directory Z on the DFS issue,entitled SrcCode. On the ADFS issue,its contents have been de-archivedready-to-run, and the programs arecontained in the directory $.SrcCode. To dearchive the DFS archive, it shouldbe copied onto a blank DFS disk alongwith the program BDARK, which is indirectory $ on side zero of the disk.Then type *BDARK SrcCode or *BDARKZ.SrcCode. The archive contains the sourcecode forthe utilities TINY, TABLE and ITALICS.The sourcecode is in BASIC, and can beloaded by LO."<filename>". ARCHIMEDES SOFTWARE In the directory Arch-SW on the ADFS Lversion there is the application!Crypter, a multitasking fileencryption program by Michael Farnworth(16C), with the encryption routineswritten in assembler. Users sending adisk for the free upgrades mentioned inthe !Help may do so via 8BS. There may also be Archimedes versionsof the Small-C demonstration programs,compiled using Acorn ANSI C Release 4.
