PIPE TAKE PIPE TAKE Syntax TAKE: TAKE FIRST LAST 1 count MSGS LINES Command Description Use the TAKE stage to specify the number of messages or lines that are passed to the primary output stream (if any). All messages or lines in excess of this number are passed to the secondary output stream. If either primary or secondary stream is disconnected, messages that would have been passed to the particular stream are discarded. Streams Stream Type Number Supported Input 1 Output 2 Termination Conditions TAKE terminates when the input stream or both output streams are disconnected. Operand Descriptions Usage Notes 234 Programming: Pipes count Specifies the maximum number of messages or lines to be passed to the primary output stream. Valid values are in the range of 0 - 10,000,000. The default is 1. FIRST|LAST Specifies whether the messages or lines to be passed to the next stage are the first count messages or the last count messages. The default is FIRST. LINES Specifies that the count is made of individual lines without regard to their grouping as multiline messages. If the indicated count is satisfied during processing of a multiline message and a secondary output is connected, then the AIFR data for the multiline message is replicated and passed to the secondary output, along with the remaining lines for that message. MSGS Specifies that the count indicated applies to whole messages, which can consist of zero or more lines. This is the default. v TAKE cannot be the first stage. v TAKE LAST delays the stream. This means that TAKE LAST produces no output until the previous stage disconnects its output stream. This causes delayed processing by stages following TAKE LAST.
Examples v TAKE LAST can affect performance because it must process the entire input stream, before it is able to send the LAST messages selected to the output stream. Example: Selecting and Displaying the Last Message To issue the VTAM command DISPLAY NET,APPLS, allow 10 seconds for each asynchronous message to return to the pipeline from VTAM, terminate the wait early (TAKE 2), select the last message (TAKE LAST 1), and display the message, enter: PIPE VTAM DISPLAY NET,APPLS | CORRWAIT 10 | TAKE 2 | TAKE LAST 1 | CONSOLE PIPE TAKE Chapter 2.
