Programs' approximate function and interesting monitor notes are listed here. In many cases Ralph merged multiple source files into a single file and collected a sample standard input file on which to run them. Many of these programs are also tweaked from the originals to produce no output; others need their output redirected to /dev/null if you don't want to wait of reams of bytes to be written to standard output.
In order to simplify the monitoring process each program prog.icn
can be compiled and run non-interactively with ./prog <prog.dat.
Some programs have empty .dat files because they do not read from &input
