The waitall command causes all command activity to wait until a
particular job completes. It effectively blocks the command line until the job and its
spawns are finished.
For jobs that require a loaddata operation, the command line waits until
the "Load Data" activity and the subsequent analysis jobs are completed.
Syntax
waitall <job>where <job> can be either a command that specifies a job or a
variable that references the command.
The examples shown for the wait command are also valid for the
waitall command.
