-In HP calculator parlance there is a distinction between **User RPL** and **System RPL**.  The former is the language directly accessible to the user of an HP calculator, whereas the latter typically requires external tools and can potentially lead to system crashes. ​ newRPL seeks to implement **User RPL** only (System RPL was used as a lower level and faster language in the Saturn processor environment or emulation layer).+In HP calculator parlance there is a distinction between **UserRPL** and **SystemRPL**.  The former is the language directly accessible to the user of an HP calculator, whereas the latter typically requires external tools and can potentially lead to system crashes. ​ newRPL seeks to implement **UserRPL** only (SystemRPL ​was used as a lower level and faster language in the Saturn processor environment or emulation layer).
  
 A typical scenario is to install newRPL on a 50g (which has the ability to replace or //flash// the operating system ROM).  Note that this procedure **completely replaces the stock HP50g ROM**, so to return the calculator to its original state would require having the HP stock ROM on hand.  A typical scenario is to install newRPL on a 50g (which has the ability to replace or //flash// the operating system ROM).  Note that this procedure **completely replaces the stock HP50g ROM**, so to return the calculator to its original state would require having the HP stock ROM on hand.
