Two more points

A) Iin the previous transcription (given by the program inout):

Gs stands for "Greek s", i. e. "sigma";
Ga stands for "Greek a", i. e. "alpha" ;
Gl stands for "Greek l", i. e. "lambda".

B) To work, when entering the four values in the "stack", the calculator should be in RPN mode.
