Can read file foirmats including tab separated values (TSV) as well as files with lines terminated Unix style. * audit identification of duplicates, gaps, audit for outliers, population summaries, data classification and stratification, univariate statistics, audit sample size computations, percentiles/quartiles, Federal holiday dates, histograms and other....

* Command line (command language)

There is no license cost for the audit software. There are some limitations, however. The software can be used for any purpose, including personal, commercial and educational, without any restriction.

System limitations. First, the design intent is for use in business applications, as opposed to science or engineering (although it might be used for those areas). There is no intentional "crippling" by system design, i.e. a limitation designed to limit the program's usefulness. I am currently in the process of testing, and removing where possible, any system limitations found which can be removed at a reasonable cost. The design target is to be able to accurately handle dollar amounts into the trillions. However, currently there can be "rounding errors" or other limitations.
