The compiler directive statements /FREE... /END-FREE denote a free-form calculation specification block. The compiler directive statements /TITLE, /EJECT, /SPACE, /COPY, and /INCLUDE allow you to specify heading information for the compiler listing, to control the spacing of the compiler listing, and to insert records from other file members during a compile. The conditional compilation directive statements /DEFINE, /UNDEFINE, /IF, /ELSEIF, /ELSE, /ENDIF, and /EOF allow you to select or omit source records. The compiler directive statements must precede any compile-time array or table records, translation records, and alternate collating sequence records (that is, ** records).
