entering data into an external eeprom (resend)

Thanks to the kind efforts of Jon Williams and Bruce Bates
I'm now communicating with and storing data on my external 256k EEprom

But not happily.

I have a huge amount of carefully calculated data to load into that
256k chip (thanks to a math program and Liberty Basic ) -- and it
looks as if my original plan to load it with DATA statements isn't
going to work.
(Well it might -- but it will take forever, since the programmer
doesn't seem to want to take too many DATA statements at a time.)

Jon Williams' Nuts and Volts articles on data logging seem to suggest
this is going to require extra hardware...

Have I overlooked something obvious, or is there really no way to
read from a file of numbers on my PC and load it effortlessly into
the external EEprom?

Cheers MacQ

    Nothing is "effortless" -- but, IMHO, this is not a difficult task all.
    Since you're skilled with Liberty BASIC I would suggest that you write
    an application that reads the file for you, then transmits the byte and
    its address to the BASIC Stamp. The BASIC Stamp would then write the
    byte for you (at the designated address) and let you know when it's
    ready for another byte (you may want to verify the write to external EE
    -- like the demo program does).

    In the end you'll have a general-purpose app that will let you transfer
    the contents of a file into an EEPROM using the BASIC Stamp as an
    intermediary.
