    Post Experimenting

    Well after much experimentation (putting a ZIF socket thru its paces)
    **my programmer and hobby testbed are two different things. I endavour to put a programmer connection on my testbed eventually, when my little spare time allows**
    i tried a 24lc256, and yes it does use a word address. Works well, or at least it appears that way.

    But leaving the code 'as is' leaves the last character of line 1 in the variable E_Byteout, and it displays this last character in the second line address range.

    So...I put together the whole thing in one line and write it (address = 0 to 18), then next read out the text on two seperate lines.(address = 0 to 10 and 11 to 18)

    My 2 questions are:
    Why can't I put 2x "Lookup" one after the other like I have in the example.
    Why won't the EEPROM record anything if I use the FOR and NEXT command to insert the address word say from 18 to 36?

    Many thanks

    **Oh one last thing. Sentence in the first section needs clarifying. My aim is not to write variable bytes into the EEPROM...instead i should be going along the lines of 'wanting to write character strings into it and then retrieving them from alternate locations' :-)
