Program listing for RPN Sunrise/Sunset

[Craig Bladow]

In the Articles section there is a listing for Program to calculate Sunrise/Sunset times. I came across a character in the program listing on line 68 (and others) that is puzzling. It looks like it should be an operator, but the section of listing below includes the other common arithmetic operators. Can someone explain what this is?
