Talk:APL (programming language)

APL at the Atlanta Public Schools

The Atlanta Public Schools Computer Center (APSCC) ran APL\360, and later APL.SV during the 1970s. I know; I maintained the system for several years. After I left the APSCC, I worked for several years at The Computer Company (TCC) in Richmond, VA, which is also mentioned in the article. Finding good refs for that history will be interesting—I wonder how many of the folks are still alive.

If I can find some sources, I'll update the article to include the APSCC info—we taught a lot of kids (and several teachers) to code in APL during that decade. — UncleBubba ^{( T @ C )} 00:30, 11 July 2020 (UTC)

APL on large vector machines

Howdy, folks!

I was a bit surprised that no mention was made of the APL*STAR programming language on the Control Data STAR supercomputer (evolved into the ETA 10 super). A description of the language can be found here: APL STAR reference manual

It's interesting from a historical standpoint because the original STAR-100 super was a wide-bandwidth pipelined vector processor. Scalar operations were essentially performed as vectors of length 1. What killed performance was the startup time for a vector operation. Something that Gene Amdahl said on the subject eludes my memory at the time. Later versions of the hardware included a dedicated scalar unit.

Snap?

Is Snap! really based on APL? Is it vandalism? 89.67.244.199 (talk) 13:21, 31 December 2023 (UTC)
