Difference between COPY and ++INCLUDE stmts

[onkarnath]

what is the difference between in using COPY and ++INCLUDE stmts in a cobol pgms?
and also give the difference b/w ++include and include++

[shriram_j]

To my experience i came to know that copy will expand the member at the time of compilation, and include only at the time of execution. And the other thing i have no idea.

Thanks

COPY is opened by COBOL compiler.
++INCLUDE is a Panvalet command to include data into a source library.
INCLUDE is opened by DB2 pre-processor.
