What is the difference between comp and comp-3 usage? Explain other COBOL usages?
Comp is a binary usage, while comp-3 indicates packed decimal. The other common usages are binary and display. Display is the default. 3/28/00 Dave Herrmann: 'I was reading your FAQ on Cobol, as an fyi Comp is defined as the fastest/preferred numeric data type for the machine it runs on. IBM Mainframes are typically binary and AS400's are packed.'

Comp, Comp1, Comp2 are used when you going to use SYNC (When you want the storage should start only at the boundaries). In other cases it depends....Venkat

COMP Comp is used for Binary Representation it allows only S and 9 ... s9(01) to s9(04) it takes 2 bytes memory s9(05) to s9(09) it takes 4 bytes memory s9(10) to s9(18) it takes 8 bytes memory
COMP-3 :- Comp-3 is used for Packed Decimal values it allows S,9 ,V mostly it is useful for Decimal Caluculation Values.
it takes (n/2)+1 Bytes Memory : for N= Even values (n+1)/2 : For n=Odd
