ALOCWAIT - ALLOCATE/WAIT			13-May-1988

This command is to provide a feature needed on VAX/VMS but not provided --
ALOCATE/WAIT.  This command allows you to attempt to allocate a device and
if it is not available, wait until it is.  In addition, multiple devices may
be allocated on 1 command.  This is especially useful for batch jobs which
need to allocate multiple tape drives/disk drives, etc.


The only qualifier added from the ALLOCATE command is the /NUMBER qualifier.
This qualifier allows multiple devices.
Multiple logical names may be specified when multiple devices are allocated.

ALOCWAIT also supports pseudo-random allocation of tape drives so the low-
numbered drives are not worked to extinction.  In this realese, that logic
applies only to allocates using MU or /GENERIC TA78.

NOTE:  ALOCWAIT must be installed with CMEXEC privilege.

Usage examples:

	$ ALOCWAIT/GENERIC TU78 DRIVE1

		This will wait for and allocate 1 tape drive

	$ ALOCWAIT/GENERIC/NUMBER=2 TU78 DRIVE1,DRIVE2

		This will wait for and allocate 2 tape drives.  Neither
		drive will be held until both become available.  This
		helps to prevent resource deadlock.
