Default Re: Interpreting a hexdump table

Quote:
Please see attached part of the table. So taking the very first address, hex 0000, the 1 byte data assigned to that address is hex 1C, and in binary form would be 0001 1100.

Taking address 040E (binary 0000 0100 0000 1110) the data assigned to that address is hex 09 ( binary 0000 1001).
Almost, but not quite. Your hex 09 value (binary 0000 1001) will be at address hex 04E, not 040E. The first row of the table shows addresses 000...00F, the second shows addresses 010...01F, and so on.

This reminds me of hand typing hex code in to my ZX81 in my youth. It was a notoriously error-prone process!
