Welcome to ACT-R/PM 2.1.2
Congratulations on successfully downloading ACT-R/PM. There should be three folders in the distribution:
Code. This folder contains all the source code for ACT-R/PM, including ACT-R itself.
Extras. Various extras, not necessarily part of the standard distribution but things you might find useful/interesting.
Test Suite. A little example of how things work in ACT-R/PM, not to be confused with a veridical cognitive model.
as well as this ReadMe file and the release notes.
Inside the "Code" folder there is a loader, called "• Load ACT-R/PM •". If you double-click that file from the Finder it should load ACT-R/PM. If the files are not compiled, this may take a while as it will compile them first. If compilation is necessary, this may generate a lot of warning messages about undefined functions. Ignore them. You should now be ready to load and run ACT-R/PM models.
If you use defsystem (which I highly recommend), copy (or alias) the file "rpm.system" to your registry. The first form in the file is the logical pathname translation for RPM, make sure this points to the correct directory for where you have installed ACT-R/PM.
Note that some systems may require that a directory called "bin" exist in the same directory as the "Code" directory.
