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.
