(80286 microprocessor) with a math co-processor and a minimum of

256 kilobytes of memory.



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

intrinsic function of the basic Fortran 77.　It is an extended

function in Mic
