For Estimating total cross sections and various spectra for complicated processes in high energy physics, the most time consuming part is numerical integration over the phase volume. When a FORTRAN source code for the integrand is produced by REDUCE, often it is not only too long but is not enough r

โฆ Synopsis
Despite the availability of many more powerful languages the majority of high-energy physics code is still written in Fortran. In addition many Fortran preprocessors are employed providing facilities ranging from simple conditional compilation and file inclusion to advanced macro translation. This paper reviews a variety of preprocessors currently in use in HEP experiments. This is followed by some specific examples of how preprocessors can be utilized to simulate language constructs and facilities missing in standard Fortran.
