Question: What is the difference between comp and comp-3 usage? Explain other COBOL usages?
Answer: 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.' |

Binary representation of data item are called 'comp', while comp-3 is the packed decimal.
comp-1 & comp-2 are another usage. |
