Examples
280 Programming: Pipes
Return Code Meaning
0 Successful completion.
12 Authorization problem.
32 DSIDKS macro failed trying to CONNECT or FIND.
40 Incorrect INCLUDE operation (%INCLUDE record normally
returned unchanged to primary output stream).

Example: Reading the Contents of a File into a Pipeline
To display the contents of the CNMCMD file as a multiline message:
PIPE < CNMCMD
| COLLECT
| CONSOLE
This example reads lines of the CNMCMD member into the pipeline. The COLLECT
stage builds these lines into a multiline message. When all lines are read from
CNMCMD and collected, the CONSOLE stage displays the multiline message to
the console.
Example: Counting Comment Lines in a File
Analyze the lines of the CNMSTYLE member.
/* REXX sample command list */
’PIPE < DSIPARM.CNMSTYLE INCL’,
’| STEM A.’,
’| LOCATE 1.1 /*/’,
’| STEM B.’
Say ’There are ’A.0’ lines in CNMSTYLE’
Say ’of which ’B.0’ are comment lines.’
This example reads the lines of the CNMSTYLE member under the DSIPARM
ddname. The contents of the expanded member are saved in a stem variable
named A. and the comment lines are located and saved to a stem variable named
B.. The messages indicate how many lines were read from the CNMSTYLE
expanded member and how many of those lines are comment lines.
