ASPL, A Set Programming Language, is an algebraic set calculator that run on the UNIX systems. The ASPL interpreter provides the premier interactive language to do algebraic set processing on set variables. It can be viewed as a general purpose set calculator that has many features to do set operations, sequence alignment operations, similarity calculations. The ASPL interpreter has the following features:

interactivity with the user

programmable with a scripting language

runs within UNIX shell and enhance your UNIX processing with additional powerful commands

provides symbolic operators and operands that uses the plain ASCII characters

computes the similarities between datasets

compares datasets by displaying their sequence alignments

joins the set operators with quotient relations and predicates

partitions the datasets

compares elements based on their entropies and checksums

provides contextual set intersection and difference for geometric datasets

compares and displays the data in colors
