IOTABLE

Purpose

The IOTABLE subcommand formats and displays a link’s RSCS I/O table (IOTABLE) chain for a specified record control byte (RCB). The IOTABLE control block defines an I/O request to write output to line or spool.

Operands

linkid: is the 1- to 8-character link identifier of the link for which you want to display IOTABLE information.
rcb: is the hexadecimal record control byte for the specified IOTABLE chain.

Sample Output

Figure 1 shows the output from the IOTABLE subcommand. In this example:

linkid: identifies the link
rcb: is the stream identifier of the IOTABLE being displayed
aaaaaaaa: is the address of the IOTABLE in hexadecimal
000, 010, 020...: are displacement values
hhhhhhhh: is the IOTABLE data in hexadecimal
eeeeee ...: is the EBCDIC representation of the IOTABLE.
