The first edition of At Play With J, collected from Eugene McDonnell’s columns for Vector has been published at Lulu.com.The first edition reproduces the original Vector articles with only minor amendments. But J has evolved over the many years during which McDonnell wrote his column, and in the latest version of J not all the examples work as given. We expect the first edition to be of largely historical interest.
Volunteer editors are preparing a revised second edition on the J Wiki. Please help them if you can.
