Identifting sign in COMP data

Hi ppl,
Can anyone tell me how to recognize whether the COMP
variables are negative or positive.
For instance in COMP-3 data , if the last nibble is 'C' then we say it
is positive and if it is 'D' or 'F' we say it is negative.

Similarly how can we recognize whether the number is positive or
negative in COMP , COMP-1 and COMP-2 data.

.
