I'm ripping my CDs into MP3 files and some files end up with inconsistent artist or album names, but fixing them with Windows File Explorer's Properties menu for each MP3 file is quite tedious. How can I programmatically read/write those properties in REXX?

I'm trying to create a mesh from stacked scans of 2D layers, each layer representing the outside perimeter of a volume scanned from the inside. I tried a PCL or XYZ file, to no avail: when I import this mesh into meshlab, nothing gets displayed. And BTW, why is meshlab continuously showing a moving progress bar in its lower right corner?
