This week features the second and concluding part of the program that will enable you to build up a database of RSX commands. The whole database can be viewed using the View RSX Database option. Using the cursor keys and the Copy keys RSX's can be switched on or switched off. Any RSX that is switched on will be included in the custom RSX extension that is created by the Save Custom RSX Table routine This option creates a file containing all the RSX's that have been switched on. Do not worry about the screen corruption whilst the routine is running The machine code is located at memory address 16384 The custom RSX file can be loaded and executed independently of the database using the following short program: 10 MEMORY 16383
20 LOAD “filename", 16384
30 CALL 16384
40 NEWThe whole database can be loaded and saved to disc or tape using the Load RSX Database and Save RSX Database options. So for example to place XEN commands in the database, load a binary file containing the XEN file using the Load Machine Code Data option and then use the Store RSX Routine option to place the commands you want into the database (eg. RSCROLL is located at 41629 and is nine bytes long) Then use the View RSX Database Option to switch on the required commands. Then, either the whole database can be saved for future use. or the custom RSX table can be saved independently. Finding out whether a particular RSX is compatible with this program may be a case of trial and error. It is worth bearing in mind that some RSX's are fundamentally incompatible with others even though they are relocatable The HEADER and SHIFTCLS commands from my XEN program are good examples. To help beginners I have compiled a list of all my RSX commands that have been published in PCW together with the memory address and length of each individual routine Readers can obtain this by sending me an SAE In addition I will provide the program on tape or disc for £3 and £5.50 respectively.

Page créée en 757 millisecondes et consultée 520 foisL'Amstrad CPC est une machine 8 bits à base d'un Z80 à 4MHz. Le premier de la gamme fut le CPC 464 en 1984, équipé d'un lecteur de cassettes intégré il se plaçait en concurrent du Commodore C64 beaucoup plus compliqué à utiliser et plus cher. Ce fut un réel succès et sorti cette même années le CPC 664 équipé d'un lecteur de disquettes trois pouces intégré. Sa vie fut de courte durée puisqu'en 1985 il fut remplacé par le CPC 6128 qui était plus compact, plus soigné et surtout qui avait 128Ko de RAM au lieu de 64Ko. |
