A simulator for certain register machines written in Scala It uses Swing for the (very simple) UI

• with an encoded program: Just input the number inside the input field and press simulate You will get back a dialog with the decoded instructions and the execution output

• with a list of instructions: The syntax for an instruction is: L#: INSTRUCTION; The supported instructions are:

  • R#+ -> L# that will incremement the register # and then go to the specified label
  • R#- -> L#, L# that will try to decrement the register #, if successful jump to the first label specified, else to the second one
  • HALT that will halt the execution of the program
