ZPWY-MAP-STATS-TERM2
ZIOS
is the number of I/O operations in which the TCP writes the data in the I/O
buffer to the TERM object. For TERM objects running in block mode, the
TCP writes output to the TERM when:
•
The buffer, defined by the ZTERMBUF field in ZPWY-DDL-DEF-TCP, is
full.
•
Executing an ACCEPT statement.
•
Any of the statements listed in ZREQCNT is followed by certain other
SCREEN COBOL statements, such as DELAY.
For devices running in conversational mode, the TCP writes output to the
terminal whenever it executes a DISPLAY statement that generates data
for a screen line.
ZACCEPT
reports TERM I/O information about the SCREEN COBOL ACCEPT
statements that the TCP executes. ZACCEPT has the following subfields:
ZREQCNT
is the number of SCREEN COBOL ACCEPT statements that the TCP
executes for the TERM object during the interval that it reports these
statistics.
ZMAXSIZE
is the size, in bytes, of the largest amount of data transferred to the TERM
object for an ACCEPT statement during the interval that the TCP reports
these statistics.
ZAGGREGATESIZE
is the total size, in bytes, of the data transferred to the TERM object for an
ACCEPT statement during the interval that the TCP reports these
statistics. To find the average amount of data transferred, divide
ZAGGREGATESIZE by ZIOS.
ZIOS
is the total number of I/O operations caused by the ACCEPT statement for
the interval that the TCP gathers these statistics.
The ACCEPT statement can cause multiple TERM I/O operations to return
advisory messages and to change screen field attributes. For some block
mode TERM objects, an ACCEPT normally requires two I/O operations—
one to read the key and another to read the data.
