The language RATMAC is a direct descendant of one of the most successful structured FORTRAN languages, rational FORTRAN, RATFOR. RATMAC has all of the characteristics of RATFOR, but is augmented by a powerful recursive macro processor which is extremely useful in generating transportable FORTRAN programs. A macro is a collection of programming steps which are associated with a keyword. This keyword uniquely identifies the macro, and whenever it appears in a RATMAC program it is replaced by the collection of steps. This primer covers the language's control and decision structures, macros, file inclusion, symbolic constants, and error messages
