Transmitting data sets
You can use the TRANSMIT command to transmit sequential or partitioned
data sets with record formats of F, FS, FB, FBS, V, VB, VBS, and U.
The data sets must reside on a direct access storage device (DASD).
For a VB or VBS data set, the largest logical record length (LRECL)
TSO/E can transmit to VM is 65,535. Data sets with machine and ANSI
print-control characters are also supported. TRANSMIT does not support
data sets with the following types of values:
- keys
- ISAM data sets
- VSAM data sets
- data sets with user labels
If a partitioned data set (PDS or PDSE) is transmitted, it is unloaded with IEBCOPY and then the unloaded version is transmitted. If a single member is transmitted, it is generally unloaded before transmission. You can force transmission of a partitioned data set member as a sequential data set by using the SEQUENTIAL operand. Forced transmission of a partitioned data set member as a sequential data set does not preserve the directory information. The IEBCOPY unload preserves directory information, but the receiver must reload it into a partitioned data set.
