I/O Info
•
Frequency distribution (optional)
Example 5-5 shows a sample set of terminal statistics. Because frequency distribution
is an optional item, this figure does not include distribution statistics. For an example of
terminal statistics showing frequency distribution, see Frequency Distribution on
page 5-25.
The TCP does not generate values for these fields: REPLY REQ CNT, REPLY I/O
CNT, CHECKPOINT REQ CNT, CHECKPOINT I/O CNT, and DATA AVG SIZE.
I/O Info
The I/O INFO section in the statistics display provides information about the I/O
operations requested by a terminal task.
These operations are requested by using these SCREEN COBOL statements:
•
DISPLAY
•
ACCEPT
•
SEND
•
REPLY
•
CHECKPOINT
Example 5-6 on page 5-19 shows only the I/O INFO section of the sample terminal
statistics.
