Transparent data being transmitted or
re~eived
may be directed to the printer. but any
EBCDIC characters less than >40 without an ASCII equivalent are not printed; any EBCDIC
characters >40 and greater without an ASCII equivalent are printed as blanks.
Transparent data (not binary) must be transmitted in fixed length records. In 990 to IBM 2780,
3780, or host· system communications, the send record length should be determined by the
receiving station's output device record lengths; the receive record length (print or punch) is
determined by the remote station•s input device record length. In 990 to 990 communication,
the record length is determined by the send record length of the transmitting station; the receive
record length should be set accordingly. Refer to table 24 for further information on transmit
and receive record lengths.
