Double word, any creative solutions?

[enigma]

Hi All

I have a project where I need to store numbers consisting of 6 digits. This obviously wont fit into a single word as is and I`m sure PBP wont support double word. Any creative ideas as to how to get around this?. In the project having stored this number I then have to do a comparison against a list of similar 6 digit numbers for a match so a solution needs to be easily sorted too.

Cheers Pete

Take the six digits, convert them to three Bytes and save them as such... eg...

Number=990714

Byte1=99
Byte2=07
Byte3=14

You can quickly scan down a huge (sorted) list in EEPROM just comparing Byte1, if it matches go on to Byte2 and if that matches go on to Byte3.

Hi Melanie!

Thanks for that, quite logical really!. I`ll have a futher play with this and see what I can make work, I only have around 30 pairs of numbers to compare and the second of the pair depend on the outcome of the match of the first.
