Auwvax.306 net.lang.apl utcsrgv!utzoo!decvax!harpo!uwvax!greg Mon Apr 5 14:30:23 1982 Request for self-replicating reference I remember seeing a wonderful recreation column in Quote Quad quite a while back, and am trying to find it again. It was about self-replicating APL expressions. I don't remember the exact definition they gave, but the basic idea is that one concocts a character vector which when given as an argument to execute reproduces itself. Other variants discussed in the article include expressions which replicate themselves and then a finite or infinite (I think) vector of duplicates of a tail of the expression. I'm pretty sure that the issue I'm looking for is more than four years ld; I looked through the back issues of Quote Quad that our library , and couldn't find it. Any leads would be appreciated.
