Comments

Comments are enclosed between pre-processor lines %comment and %end . These lines are then ignored when the file is being pre-processed, either for running the job or for the manual-page. You cannot, however, comment-out a part of the manual page.

Since comments are processed before a job is created they can be placed anywhere in the script. Just remember that comments do not nest and that you cannot use comments inside manual pages. (You can, of course, change the %manual to be %comment )

The following extract is an example of using comments:

mars << EOF
    RETRIEVE,
    PARAM=10U/10V,DATE=...,
%comment
    temp mod by OP / 1.1.2012 BC
    TARGET="/xx/yy/zz",
%end
    TARGET="zz",
    END
    EOF
    And the following is the corresponding output when pre-processed.
    mars << EOF
    RETRIEVE,
    PARAM=10U/10V,DATE=...,
    TARGET="zz",
    END
EOF
