Is this your actual code? If so, maybe there's a syntax problem? Seems like the above example should be:

    open file blabla for reading

    -- read the last 100 bytes (or last 99?)
    #read from file blabla for -100
    read from file blabla at -100 for 100

    put the result into r
    put it into x
    close file blabla

FWIW. I didn't test my suggestion, so be careful!
