Tryon, Bailey et al. (~1965).  BCTRY user’s manual. This version of the BCTRY manual is derived from an ALL-CAPS copy that was created on IBM punch cards and then transferred to computer tape. Much of this text was converted to Upper/Lower case in the 1980s.  More recently, sections of the Manual not available earlier were scanned from a printed copy and added to create the current version.
