compress: Compress reduces the size of the named files using adaptive Lempel-Ziv coding. The amount of compression obtained depends on the size of the input, the number of bits per code, and the distribution of common substrings. Typically, text such as source code or English is reduced by 50-60%. Compression is generally much better then that achieved by Huffman coding (as used in 'pack') or adaptive Huffman coding (as used in 'compact'), and takes less time to compute. Great for saving disk space, or reducing transmission time over phone lines! Also includes 'btoa' and 'atob' for converting binary files to ascii, and then back to binary (for transmission over links that donot support 8 bits).

dadc: A digital computer impersonating an analog clock impersonating a digital clock.

microemacs: An upgraded version of microemacs originally distributed on disk number 2. New executable is about 25% larger. One enhancement is that some functions are now also bound to function keys.
Author: Dave Conroy, with enhancements by Jack Roose.

mult: Mult reads the input comparing adjacent lines. In the normal case, the second and succeeding copies of repeated lines are output, and the remainder of the lines are removed. Repeated lines must be adjacent in order to be found. Options are present to output the first of multiple lines, for comparing adjacent lines by field only, and for specifying the field separator character. Kind of the opposite of the Unix 'uniq' program.

scales: Demonstrates use of the Audio functions in the ROM to produce four voice sound. It uses a simple waveform(sawtooth) with no amplitude control (ie, envelope)or frequency variation (ie, vibrato), but these can be easily implemented. Also includes considerable documentation on audio device.

setparallel: Allows the CLI user to dynamically change any particular parallel port parameter.
Author: Keith Stobie and Tom Pohorsky

setserial: Allows the CLI user to dynamically change any particular serial port parameter.

sortc: A quicksort based sort program, using separate driver and sort modules. Originally from a DECUS C distribution. Claims to be fast, but when operating entirely out of ram takes 93 seconds to sort its input file, sort. c, while Amiga Dos's sort takes only 43 seconds under the same conditions.
Author: Dave Conroy, Martin Minow, and Ray Van Tassle

stripc: Strips comments and extraneous whitespace from C source files. Useful for compacting the C header files to increase usable disk space.
