hi everyone.
im trying a memory intensive app on a 18f2620, where i need to read/write ascii characters onto eeprom. this pic has 1024 eeprom bytes, but for some reason, i cannot read/write beyond address 255.

program compiles ok but it shows black pixels on an lcd when i use this command:

data @300, "a","s","c","i","i"

i try to read at any of the above locations, and i get no values. works ok if i use any address under 255.

what im i missing?

thanks for reading
