Table 3-12. Block Mode Without Blocking SEND Command Block Formats
Normal-Text Block Format
All blocks except last: STX record ETB
Last block: STX record ETX
Maximum block size: 4086 bytes (includes 1 byte each for STX and ETB/ETX)
Maximum record size: BLOCKSIZE
Block mode without blocking treats each block as a single record. It does not support the use of ITB
characters or IRS characters as record separators within a block.
Records cannot contain any BSC control characters.
Transparent-Text Block Format
All blocks except last: DLE STX record ETB
Last block: DLE STX record ETX
Maximum block size: 4087 bytes (includes 1 byte each for DLE, STX, and ETB/ETX)
Record size: BLOCKSIZE (maximum)
Records can contain any character (bit pattern).
Note that for transparent-text block format, all DLEs other than the first DLE are
inserted in the block by the underlying communications subsystem. Therefore, these
DLEs do not appear in Exchange/RJE trace data. (A DLE as data is sent as DLE DLE.
The additional DLE is inserted by the underlying communications subsystem.)
Files With Blocked Records
The SEND command cannot read and send a send file that contains blocked records,
such as many tape files. If the file you want to send contains blocked records, you
must first unblock the records before you can send the file to the remote system. You
can use the File Utility Program (FUP) to unblock the records. For information on
FUP, see the File Utility Program (FUP) Reference Manual.
Examples 1. This example shows the simplest form of the SEND command.
