For read operations, WRITEREAD works exactly the same as READ. See the READ
procedure earlier in this section for the line activity associated with a read operation.
Considerations The WRITEREAD procedure writes a record from your program to the Exchange/RJE
line server for transmission to the remote system or reads a record received by the line
server from the remote system.
For write operations, the WRITEREAD procedure is functionally the same as the
WRITE procedure. For considerations regarding write operations, see the WRITE
procedure earlier in this section.
For read operations, the WRITEREAD procedure is functionally the same as the READ
procedure. For considerations regarding read operations, see the READ procedure
earlier in this section.
If you opened the Exchange/RJE line server for nowait I/O, you must call AWAITIO
to complete an I/O operation initiated by a call to WRITEREAD.
