Today is the 45th anniversary of the APL language as an actual computer system.
You can get more information on this from the following links:
- A PERSONAL HISTORY OF APL by Michael S. Montalbano
- It’s APL’s Birthday! Or is it? by Catherine Lathwell
At APL’81 a number of us participated in a sing-along of Michael’s “APL Blossom Time” that includes the title of this post. You’ll find the lyrics in Appendix A of his document.
