one more question

in comp
how they are saying 9(4) means 2 bytes??

Data name length Length in COBOL
9(01) to 9(04) 2 bytes
9(05) to 9(09) 4 bytes
S9(10) to S9(18) 8 bytes

And don't define it as COMP, use COMP-5, for sure if you variable data may be greater than 9999 bytes, and it is good practice for the next copy/paste.
