I am currently reading the OSLO Optics Reference 6.1 manual. On page 11 of the hardcopy version (page 20 of the electronic version),

I am asked to open the "Landscape 1.len" file. I don_t seem to have this file. Where do I find it?

Synopsis

Locating the Landscape Lens file

Solution

Unfortunately, portions of that manual is out of sequence. On page 11 (page 20 for the electronic version), we ask that you open a file, but the steps to create and save the file begin on page 28 (page 37 for the electronic version). We suggest that you follow the steps and complete the exercise starting on page 28 (37) first. This error will be corrected in a future release of the OSLO Optics Reference Manual.
