Oh wow. This is a bit hard for me. You see, I came from VB and moved/incorporated J because VB cannot do easily what I want to do with arrays.
Just retrieving a column from a 2 dimension array requires walking through the array row by row. Another one is that when I was looking for info/documentation on J so that I can learn it ... I have not found any public documentation that covers what your looking for. The thing is, I actually wrote one to that effect called J for C# programmers which I patterned from the publicly available book J for C programmer by Henry Rich. Unfortunately, I cannot give you a copy of the guide I wrote since its effectively owned by the company I work for. Besides, I use it for training so there is a lot to be desired ... Thinking about it, I would suggest taking a look at Henry Rich book (J for C programmer) and it may help you categorized the J language and maybe later on create your own VB/VBA library that mimics the capabilities of J. :D r/Alex -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Richard Hill Sent: Tuesday, August 11, 2009 1:11 PM To: 'Chat forum' Subject: Re: [Jchat] iverson VB >Can you clarify what you're looking for? >r/Alex Alex, thank you for your interest. Assume that you know J / APL and you don't know VB. You have to use VBA by direction from above. VBA has arrays and the 'variant' type. You think that you can use Iverson's ideas. The first thing you need is a dictionary. Eg tally in J is translates to ubound() in VBA Then you need a set of functions that perform operations on arrays using Iverson's terminology. What I am looking for is any write up and/or other work addressing this area.
