If a COMP field is signed, then FI is the correct format.

If a COMP field is unsigned, then BI is the correct format. CH can also be used as long as options that affect CH (like ALTSEQ or LOCALE) are not used. BI is safer.

For example:

If X'FFFF' represents -1, then the COMP field is signed and FI should be used.

If X'FFFF' represents 65535, then the COMP field is unsigned and BI should be used.
