3/15/72 PTX (VI) NAME ptx -- permuted index SYNOPSIS ptx1 input temp1 sort temp1 temp2 ptx2 temp2 output DESCRIPTION ptx generates a permuted index from file input on file output. It has three phases: the first does the permutation, generating one line for each keyword in an input line. The keyword is rotated to the front. The permuted file must then be sorted. ptx2 then rotates each line around the middle of the page. input should be edited to remove useless lines. The following words are suppressed: "a", "and", "as", "is", "for", "of", "on", "or", "the", "to", "up". The index for this manual was generated using ptx.
