REQUEST                                                  CP Privilege Class:  G

Use the REQUEST command to make an attention interrupt pending at your virtual
console.  The format of the REQUEST command is:
+----------+------------------------------------------------------------------+
| REQuest  |                                                                  |
+----------+------------------------------------------------------------------+


Usage notes:

1.  The REQUEST command performs the same functions as ATTN and the two
    commands can be used interchangeably.

2.  CP ignores the REQUEST command if any I/O operation is in progress at the
    console or if other interrupts are pending.  This condition may result if
    the user issues the REQUEST command by means of DIAGNOSE X'8'.
