Ralph E. Griswold · 1990
Version 8.10 of Icon for MS-DOS should run on any PC or PC clone running MS-DOS 3.0 or higher. A math co-processor is supported and used if present; otherwise software emulation is used. Approximate 500K of free RAM is needed to run Icon satisfactorily. Two versions of Icon’s executor system are provided. One supports arithmetic on integers of unlimited magnitude and the other does not. The latter is considerably smaller than the former
