The header on the first page of a source listing contains the identification of the compiler and the current release level, the date and time of compilation, and the page number.
The following example shows these five elements:
PP 5655-S71 IBM Enterprise COBOL for z/OS 4.1.0 Date 12/30/2007 Time 15:05:19 Page 1
The header indicates the compilation platform. You can customize the header on succeeding pages of the listing by using the compiler-directing TITLE statement.
