TIMESTAMP
NOTIMESTAMP
excludes date and time comments from source code listings.
The DDL compiler produces a number of starred timestamp comments on the listings
of DDL or host-language source code. A comment at the beginning of the listing tells
the date and time the schema was produced; individual comment lines preceding each
section tell when each DDL object was created.
You can suppress these timestamp comments with NOTIMESTAMP and then include
them with a subsequent TIMESTAMP.
Example 9-60 on page 9-114 shows selective listing or suppression of the timestamp
comments in a COBOL source code file.
