No, PIC9(5) is a 3 byte field - 5 digits + sign - each of which is 4 bits long.

When a PIC9(5) field is included in a record the compiler might insert
a 'padding' byte so that the next field starts on a 'word' boundary.

I'm fairly certain that IBM COBOL pads records, I don't know about ACCUCOBOL.

 It is probably a header record.
