This utility, which bears the Amstrad's original name, will help with investigations into memory. The machine's ROM routines can be looked at or any program which can co-reside in RAM can be examined. Memory can be modified, saved or loaded. Command summary View Memory. Asks for the start and finish locations, which have to be decimal. The memory contents will then be displayed in blocks often. ‘Space' steps through to the‘finish'. ‘Text' can be read from the ASCII columns. Checksum. Asks for the start and finish. All the values are then totalled in decimal, inclusive of the addresses entered. This option is useful when entering from a listing which provides a ‘Checksum' to check if errors have occurred. Modify mem. Again the start and the end addresses are required. Then the display shows the current value. Pressing ‘Enter' will retain this value and the next location will be displayed. Typing numbers followed by ‘Enter' will put what is typed into the current address. If the value is invalid then this will be indicated and no changes will be made to memory. The next location will then be shown. Great care should be taken, since any RAM may be modified with perhaps surprising results. (All entries arc in decimal.) Save. Asks forstart and finish (decimal), then the file name. Saving commences when ‘Enter' is pressed. ‘Record' and ‘Play' should be pressed prior to selecting the ‘Save' option. Load. This, when followed by pressing‘play', loads the first file found. ‘Shift' ‘Q' will quit any option.
