On the ZX Spectrum Next, the EXTEND key functions as a control (CTRL) key, so to press CTRL-S (for example), hold down the EXTEND key and press the S key. You can also hold down CAPS SHIFT and SYMBOL SHIFT together, instead of EXTEND. A few keys have special meanings to this program: CTRL-A (Cursor left) Reset the terminal and show the previous screen CTRL-F (Cursor right) Reset the terminal and show the next screen CTRL-C Exit the program Any other key pressed whilst this program is active will be sent directly to the terminal, allowing you to type control codes or escape sequences and see the effects that they have. By default, the terminal provided is 24 lines by 80 columns, which is suitable for most CP/M software. If desired you can change the terminal size using the TERMSIZE.COM program to anything up to 32 lines by 80 columns. ``` *Fig. 30 – TERMINFO output* ### Drives and CP/M *CP/M* on the ZX Spectrum Next cannot access the standard SD card drive **c:** (or other drives you may have due to having additional SD cards inserted, for example). This is because *CP/M* directly accesses disks at a low level, and is incompatible with *FAT filesystems*. Therefore, on the ZX Spectrum Next, *CP/M* uses *virtual disk* files. These can either be **.p3d** files (created by the **.mkdata** *dot command*) or **.dsk** files (images of standard ZX Spectrum +3 disks). You can access multiple disk images at once in *CP/M*. To do this, simply create additional files with **.mkdata** using the same naming scheme. eg. at the *NextZXOS* command line, type the following: ``` .mkdata "/nextzxos/cpm-b.p3d" .mkdata "/nextzxos/cpm-e.p3d" ``` When you next use *CP/M*, you will have drives **A:**, **B:** and **E:** available. Note that you can have a drive **C:** in *CP/M* if you wish, but this is not the same as the **c:** drive used in *NextZXOS*. Up to **15** *virtual disk images* can be used at once by *CP/M*, and they can be mapped to any drive **A** to **P**, simply by naming the files in any of these ways: ``` c:/nextzxos/cpm-X.p3d c:/nextzxos/drv-X.p3d c:/nextzxos/cpm-X.dsk c:/nextzxos/drv-X.dsk ```
