- DESCRIPTION -

The program provides the following facilities:
Query Memory - displays a row of eight bytes of data in hex, starting with the specified address. Hitting Space displays the next eight bytes, and Enter will terminate the command.
Edit memory - displays the specified address in hex and the data held there, also in hex. Enter will step to the next address without changing any data, and ^ - unshifted £ - will step backwards to the previous address, again without changing any data. Entering a byte of data, i.e. two hex digits, will cause that value to be entered at the current address. The two digits are entered without a preceding &. Entering a q will terminate the command.
Breakpoint - sets or clears a breakpoint. If setting, then a four-digit hex address is requested, if clearing, the address is remembered and cleared automatically. On encountering the breakpoint, the contents of all the registers are displayed - except for the alternate register set, which Amstrad discourages the use of.
Goto - executes a machine-code program from a specified address.
Load - loads a named binary file from cassette.
Save - saves a named binary file to cassette.
Except for data entry during the edit command, all values must be entered in hex and preceded by the & character.
