The source code of ISORROPIA is written primarily in FORTRAN 77. The only extensions to the ANSI standard implemented were the usage of INCLUDE statements, trailing comments, and variable names with length larger than 6 characters (but not larger than 9). These extensions are supported by the majority of FORTRAN 77 compilers, and are also included in the Fortran 90 standard, so they should not pose any portability problems.
The model has extensively been tested on many platforms (DEC Alpha, HP and IBM RISC workstations under UNIX, Intel-based PC’s under MS-DOS and Windows 95) and compilers (both FORTRAN 77 and Fortran 90). The results during these tests were found to be independent of the system used.
