To type a decimal value in ISPSoft, type it directly. To type a hexadecimal value in ISPSoft, type “16#” and the
hexadecimal value; e.g. 16#7FFF. In ISPSoft, 8# precedes an octal value, and 2# precedes a binary value.

diagram is colored red while you write the program. The following sections show how to compile and download
the compiled program for testing.
