If you specify NOTRANSPARENT and NOTRANSLATE, the data is
transmitted as transparent text and the data is not translated before it is
transmitted. NOTRANSLATE always takes precedence over
NOTRANSPARENT or TRANSPARENT.
Whenever the data is transmitted as transparent text (TRANSPARENT or
NOTRANSLATE is specified), the data must be in fixed-length, 80-byte
records (except for block mode without blocking).
If you omit this parameter, the default value is NOTRANSPARENT.
TRU[NCATE] | NOTRU[NCATE]
controls the truncation of trailing blanks.
If you specify TRUNCATE, trailing blanks are removed from each record
before the record is transmitted.
If you specify NOTRUNCATE, trailing blanks are not removed and each
record is transmitted with trailing blanks included.
If you omit this parameter, the default value is NOTRUNCATE for 2780-
emulation mode (and block mode with 2780 blocking) and TRUNCATE for
3780-emulation mode (and block mode with 3780 blocking).
TRUNCATE is ignored for block mode without blocking.
This parameter is ignored if you specify either NOTRANSLATE or
TRANSPARENT; transparent text does not allow trailing-blank truncation.
Line Activity The SEND command begins by bidding for the line (sending an ENQ to the remote
system). After the bid has been accepted (the remote system responds with an ACK 0),
the SEND command transmits the send file to the remote system.
The SEND command reads the send file one record at a time. The records are
assembled into blocks. Each block is transmitted to the remote system as a single unit.
The remote system must acknowledge the last block before the next block is sent. If
the remote system responds to a block with a negative acknowledgment (NAK), which
indicates an error occurred during transmission, the last block is transmitted again.
After the remote system has acknowledged the last block of the send file, the SEND
command transmits an EOT, which signals the end of the transmission. This causes
Exchange/RJE to relinquish control of the line and places both Exchange/RJE and the
remote system in the control state. Before either Exchange/RJE or the remote system
can transmit again, a successful bid for the line must occur.
For a description of the block and record formats that Exchange/RJE transmits, see
“Block and Record Formats” below.
