[AmigaOS 3.1 Command Reference/ChangeTaskPri] 
 
 
 CHANGETASKPRI
 
  
 Format:	CHANGETASKPRI <priority> PROCESS [<process number>] 
  
 Template:	PRI=PRIORITY/A/N, PROCESS/K/N 
  
 Purpose:	To change the priority of a currently running process. 
  
 Path:		C:CHANGETASKPRI 
  
 Specification: 
  
 Since the Amiga is multitasking, it uses priority numbers to determine the 
 order in which current tasks should be serviced. Normally, most tasks have a 
 priority of 0, and the time and instruction cycles of the CPU are divided 
 equally among them. CHANGETASKPRI changes the priority of the specified 
 Shell process. (If no process is specified, the current Shell process is 
 assumed.) Any tasks started from <process number> inherit its priority. 
  
 Use the STATUS command to display the current process numbers. 
  
 The range of acceptable values for <priority> is the integers from -128 
 to 127, with higher values yielding a higher priority (a greater proportion 
 of CPU time is allocated). However, do not enter values above +10, or you 
 may disrupt important system tasks. Too low a priority (less than 0) can 
 result in a process taking unreasonably long to execute. 
  
 Example: 
  
 1> CHANGETASKPRI 4 Process 2 
  
 The priority of Process 2 is changed to 4. Any tasks started from this 
 Shell will also have a priority of 4. They will have priority over any 
 other user tasks created without using CHANGETASKPRI (those tasks will 
 have a priority of 0).
