 *
 *  OVERVIEW
 *
 *    HSTCOPY READS A FILE AND TRANSFERS IT TO A 5870 OR 5970
 *    NON-IMPACT PRINTER.  HSTCOPY CALLS THE PP PROGRAM XHC TO
 *    TRANSFER THE DATA TO THE NON-IMPACT PRINTER.
 *
 *    HSTCOPY READS THE FOLLOWING TYPES OF FILES:
 *
 *      1) RECORDS CONSISTING OF MULTIPLES OF 128 8-BIT BYTES,
 *         WITHOUT ZERO-BYTE TERMINATORS, UP TO A MAXIMUM
 *         OF 8192 8-BIT BYTES.
 *
 *      2) 80-BYTE EBCDIC CARD IMAGE RECORDS WITHOUT ZERO-BYTE
 *         TERMINATORS.
 *
 *  CONTROL STATEMENT CALL
 *
 *    HSTCOPY(INPUT,OUTPUT,FTS)
 *
 *      HSTCOPY           - HOSTCOPY CONTROL STATEMENT.
 *      INPUT             - INPUT FILE CONTAINING INPUT DIRECTIVES.
 *      OUTPUT            - OUTPUT FILE CONTAINING STATUS OF HOSTCOPY.
 *      FTS               - INPUT FILE TO TRANSFER TO NIP.
