NAME

CONSTANTS - constants for LAM Fortran programming

DESCRIPTION

The following table describes the values appropriate to various constants used in LAM. It also describes the meaning of the constants and lists the cpp(1) header files in which the constants can be found. To use these files, the Fortran source files will need to be passed through cpp(1) before they are given to the Fortran compiler. Some compiler drivers will run cpp(1) if the source file suffix is .F.
In lieu of cpp(1), the constants can be copied to parameter statements in the Fortran source files.
