Digital Equipment Corporation
The PDP-11 SORT Reference Manual (AA-3341C-TC) described the features and operation of the SORT utility program that allowed the user to read any input file, to sort the contents with four sorting techniques (record sort - SORTR, tag sort - SORTT, address routing sort - SORTA, and index sort - SORTI) and to write out the sorted data onto an output file. The manual applied only to operating systems RSX-11M versions 3 and 3.1, RSTS.E version 6B and IAS version 2 as well as software SORT-11 version 2.
