***************************************************************************** Depending on the capacity of the disk drives you are using, you may only have room to compile two or three programs at a time because the compiled programs will reside on the program codes disk after compilation. If this is the case, copy the compiled versions of the programs (those ending in .EXE) onto another disk and erase all files with .OBJ or .EXE extensions on the program codes disk. You will then have room to compile more programs. The program SUP_H2O is very long and may have to be compiled on a separate disk. Copy the program codes disk onto a blank disk and erase all files ending in .FOR except SUP_H2O.FOR. You will then have enough room left for the compiled SUP_H2O. The first step to begin compiling is to put the disk containing the program codes in drive B (the right-hand drive on a dual-drive PC or the lower drive on a dual-drive PC-AT). The second step is to put the disk containing your working FORTRAN compiler in drive A (the left-hand drive on a dual-drive PC or the upper drive on a dual-drive PC-AT). DO NOT BEGIN THIS PROCEDURE UNTIL INSTRUCTED TO DO SO *****************************************************************************
