/RESOURCE_WAIT
       /NORESOURCE_WAIT

    Enables resource wait mode so that the process waits for
    resources to become available. If you specify the /NORESOURCE_
    WAIT qualifier, the process receives an error status code when
    system dynamic memory is not available or when the process
    exceeds one of the following resource quotas: direct I/O (DIOLM)
    limit, buffered I/O (BIOLM) limit, buffered I/O byte (BYTLM)
    count limit (buffer space), timer queue quota, mailbox buffer
    quota, or pipe quota.

                                 CAUTION

       Disabling resource waiting should be performed with caution,
       as doing so can have unexpected effects on constituent
       sharable images and runtime libraries. See the $SETRWM
       service in the VSI OpenVMS System Services Reference Manual
       for additional information.
