Sorting blocks of data in EEPROM

[dhouston]

Dave, the 2nd method you describe is pretty much what I'm trying to achieve; since the records are all fixed at 6 bytes each, I too concluded that it would be easier this way. Now, there are no macros here; just simple on and off times tied up with a unit address. So, when I punch in these 6 bytes thru' Hyperterminal, how do I make the existsing entries (if any) accomodate the new one, and sort it by the first byte of the record, the address code?

Anand,

I just use a sorted listbox in the Windows program I write with VB and I rewrite all of EEPROM whenever I insert a new entry. I'm not sure how I would go about it using hyperterminal. Are you looking to use PIC code to sort them in EEPROM?

While it depends on your EEPROM, most EEPROMs can be written to a hundred or more times a day without any danger of wearing out. If you need more frequent writes, use FRAM which can withstand billions of erase/write cycles.
