The APL Wiki Tutorial contains several references to NARS2000 regarding extraordinary behaviour and/or missing features. See http://aplwiki.com/LearnApl/LearningApl

The following shall be a complete list of those issues. Used to make changes to the wiki when appropriate.

Chapter 6: "Writing a Function"

"Saving a workspace"

Using Windows default folder (NARS2000) versus current directory (other implementations).

Chapter 10: "Built-in Functions"

"Comparative Functions"

"Find" is not available

Chapter 14: "Error Handling"

Error trapping and Tracing

Currently NARS2000 offers both ⎕ELX Error Latent Expression and ⎕EA Execute Alternate for error trapping, two very helpful exception-handling / run-time-error-avoidance features, when used correctly.
See also Examples/Files for a user-function example of ⎕ELX use. Default value for Quad ELX: ⎕ELX←"⎕DM"
