Test Compression Facility

The Test Compression Facility (TCF) is a batch program that allows you to determine the best data compression algorithm to use for each file you want compress. Under the control of SYSIN control statements, TCF analyzes data sets and provides statistical projections of the savings (in kilobytes and DASD tracks) to be realized through Huffman and Super Express compression. TCF enables users of CA Compress to determine which individual data sets are the best candidates for processing, and to project the storage savings.

The TCF is an alternative to the Interactive User Interface (IUI), but the IUI is usually more convenient.
