'WP' Wait for Pipe on Close
Description
(UNIX/Linux Only)
Determines whether or not to wait until a child process completes. When the 'WP' parameter is On and a pipe is closed, PxPlus will wait until the child process has terminated.
When the 'WP' parameter is Off and a pipe is closed, PxPlus will not wait for the child to complete. This can result in a child process that has not had its exit status checked (shown as "defunct"). PxPlus will automatically check and clear out these defunct processes whenever a) it opens another pipe, b) a WAIT directive is encountered, or c) the current PxPlus session is terminated.
Default
Off
