• HP 48S/SX
  It is located on blue-shifted above "2" key, and labeled ARG (with LAST on white above it)
• HP 48 G/GX/G+
  It is located on blue-shifted above "EEX" key, and labeled ARG
  

On the HP 50g it is called ANS on the keyboard (left-shift ENTER). Confusingly there is also an ARG on the keyboard (right-shift /) but that is the argument (polar angle) of a complex number.
