UCalc emulates the User-RPL programming and debugging capabilities of the HP programmable calculators.  With UCalc, you can run and debug your User-RPL programs, display GROBs in color and keyboard key labels from your programs.  The inputs to UCalc¹ is the User-RPL 'projects' you develop using the UEdit User-RPL Program Development Tools.  Upgrade UCalc to UCalc Advanced Edition to open unlimited multiple projects to make UCalc functions like the real HP calculator!  UCalc is a standalone PC application.  No calculator or calculator firmware is needed to run UCalc.

Download UCalc ¹ Microsoft Windows Vista and XP.  Requires Microsoft .NET framework 3.5 available free from Microsoft download site.
