Thanks for your contribution.

You've probably not noticed, but the repository contains these programs for other languages too (for example, factorial.dana for the Dana language) and there are already symbolic links to input and result files for these programs. I suggest that you modify these two PCL programs to have similar input/output behavior to the Dana ones and add symbolic links to the corresponding .input and .result files in the pcl/programs directory instead of new files there. Do these changes and I will merge the PR.
