System request (often abbreviated SysRq or Sys Req) is a key on keyboards for PCs that has no standard use[1]. This key can be traced back to the operator interrupt key used on IBM 3270-type console keyboards of the IBM System/370 mainframe computer[citation needed], which was used to cause the operating system such as VM/370 or MVS to allow the console to give input to the operating system.
