This article was previously published under Q27211 SUMMARY
Microsoft FORTRAN provides a random number generator in versions 5.0, 5.01,
and 5.1. It is documented on pages 272-273 of the Microsoft FORTRAN
"Reference" manual for versions 5.0 and 5.1. Even though previous versions
of Microsoft FORTRAN do not provide a random number generation function,
there are at least two methods to generate random numbers in FORTRAN
versions 4.0, 4.01, and 4.1.
The DEMORAN.FOR file demonstrates a uniform random-number generator for
FORTRAN. DEMORAN.FOR is distributed on the Utilities and Source Code Disk
(disk 3 or 6) in FORTRAN versions 4.0 and 4.01 and on the Setup disk for
version 4.1. Comments at the beginning of the DEMORAN.FOR file provide
documentation.
The other method involves using the mixed-language programming capabilities
of Microsoft FORTRAN. Call a Microsoft C or QuickC run-time library to
access the rand() function in the library routines.
