Deletes a formqueue.
formqueue is the name of the formqueue to be deleted.
A formqueue cannot be deleted if the formqueue is not empty or the formqueue is assigned to logical device type.
The formqueue should be changed to a device type of zero and any print jobs either deleted or reassigned to another formqueue. Any processes currently assigned to the deleted formqueue will change to NO QUEUE and any attempt to spool a job will display an error message.
