'''Note:'''
* The <code>|</code> symbol can be obtained by pressing SHIFT and “@” (at) together on the Amstrad keyboard.
* The <code>|</code> symbol is only valid for Amstrad computers with an English or Spanish ROM. With French ROM, the <code>ù</code> symbol has to be used instead. With Danish ROM, the <code>ø</code> symbol has to be used instead.
* The CPC664, CPC6128 and CPC6128+ have a disc interface built-in, and this command must be used to enter cassette mode.
* The CPC464 and CPC464+ have a cassette player built in. If you have a disc interface (Amstrad/Schneider DDI-1 or Vortex) connected you will need to type this command to enter cassette mode. If you do not have a disc interface, you do not need to type this command.
