Can you give me an example how I can change to "da" and then unpack please?
in the offending macro find the word "data"

delete the t and and one of the remaining a's in that word


to unpack

read in the low byte , store bit 7 value of low byte then bitwise and (&) the low byte with 127
then
read in the high byte left shift it left 1 digit then add 1 to result if bit7 result from low byte is not zero
