Disk Contents: GRWAVE is supplied on a 3.5" or 5.25" disk which contains three main files. These are GRWAVE.EXE, GRWAVE.FOR and GRWUSR.MAN. GRWAVE.EXE is executable machine language code. GRWAVE.FOR is the FORTRAN source code. Compilation of this source code to produce an executable code requires a FORTRAN compiler which supports double precision complex arithmetic. Microsoft FORTRAN Version 4.01 was used to compile and link GRWAVE.FOR to produce GRWAVE.EXE. Compilation has also been tested with Lahey FORTRAN F77L [*]. It is known the IBM Professional FORTRAN will not work because of a lack of support for double precision complex arithmetic. [*] Note: GRWAVE uses a function, DREAL, which is not an in
