I am not seeing any visualizations or graphics in Example N03. I get an error message "macro file <vis.mac> not found" before I am dropped to an "Idle>" prompt. I have chosen X Windows as my GUI, per section 1.3 of the Installation Guide. Section 8.6 of the User's Guide for Application Developers does not mention X windows.
You are expected to execute your program at the directory where "vis.mac" exists. Please confirm on which directory you are trying to execute your program.
