Hi! I have been using tacit programming for some time. It is not unusual that difficulties arise due to my shallow understanding of the J language.
The current problem can be demonstrated with a simple example: I want a doubling function that takes two parameters. The first one is the number to be doubled and the other one tells how many times. Like: +:^: (<3) 5 5 10 20 How can I do it tacitly, i.e.: 5 multidbl 3 should give the same result? The problem appeared when I finally began to program my own life :) inspired by this demonstration and FinnAPL Tallinn conference in Estonia starting on Wednesday (and yes, there are three J-related presentations, all by our Estonian friends). www.youtube.com/watch?v=a9xAKttWgP4 I actually got this generation function working somehow but it annoyed me that I couldn't give the nouns in the same order as in the presentation, life matrix on the left side and generation count on the other. This one was ok: gen=.life^:[] 3 gen R I tried to understand the problem by writing a much simpler function but didn't get it working tacitly at all. I also tried to find some information from the documentation but didn't recognize any. It would be nice to get my own life working before looking for better life :) .
