Argument

 

watflg

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value
   Indicator specifying whether system services should wait for
   required resources. The watflg argument is a longword value. The
   value 0 (the default) specifies that system services should wait
   until resources needed for their execution become available.
   The value 1 specifies that system services should return failure
   status immediately when resources needed for their execution are
   unavailable.

   The operating system enables resource wait mode for all
   processes. You can disable resource wait mode only by calling
   $SETRWM.

   If resource wait mode is disabled, it remains disabled until it
   is explicitly reenabled or until the process is deleted.
