PIPE COUNT
60 Programming: Pipes
Operand Descriptions
Usage Notes
BYTES
Specifies that the total bytes in all messages received on the input stream are to
be passed to the primary output stream. Both leading and trailing blanks are
counted.
EACHLINE
Specifies that COUNT set a line attribute in each message line indicating the
line's position within the data stream. The modified line is passed to the
primary output stream. A secondary output stream is not supported.
The line attribute can be accessed with EDIT LINECOUNT and CONSOLE
DUMP.
The line attribute remains unchanged in the pipeline and in safes created by
the SAFE stage. However, commands executed subsequently in the pipeline
can change the line count attributes.
See “Example: Line Counts Reset by Command” on page 61 for information on
modification of set line attributes, see HELP PIPE EDIT for information on the
EDIT stage, and HELP PIPE CONSOLE for information on the CONSOLE
stage.
Note: Do not use EACHLINE if the processed messages are to be used with
the REPLY command.
EACHMSG
Specifies that COUNT set a message attribute in each message indicating the
message's position within the data stream. The modified message is passed to
the primary output stream. A secondary output stream is not supported.
The message attribute remains unchanged in the pipeline and in safes created
by the SAFE stage. However, message count attributes are reset if the message
is processed by a NETVIEW or CORRCMD stage.
FROM
Specifies the initial value for the counter. The default is zero.
LINES
Specifies that the total number of lines in all messages received on the input
stream is to be passed to the primary output stream.
MAXLINE
Specifies that COUNT counts each message line passed to it and returns the
number of bytes contained in the longest line. Both leading and trailing blanks
are counted.
MESSAGES
Specifies that the total number of messages passed on the input stream is
passed to the primary output stream.
Each multiline message is counted as one message.
MINLINE
Specifies that COUNT counts each message line passed to it and returns the
number of bytes contained in the shortest line. Both leading and trailing blanks
are counted.
v If you do not want leading and trailing blanks to be counted when using
COUNT BYTES, add a STRIP stage before the COUNT BYTES stage.
