Look at c0`c1`c2/ p0;p1;p2;''

Suppose I wish to construct a complex, non-regular deeply nested structure: to model some inherently non-linear system. A natural approach (for me, anyhow) is to construct a library of combinators, or a domain specific language, with which to specify the (boxed) structure. J rises easily to the task, and before long I'm looking at long function trains of the form myStruct =: c0 p0 c1 p1 c2 p2 ... cN pN where the ci are (combinator) verbs, and the pj are (parameter) nouns. Nice. Easy. Only trouble is, N may be large and J prefers such statements to sit on a single line. Correct? I can split my definition: msPartA =. ..... msPartB =. ..... ..... msPartX =. ..... myStruct =: msPartA msPartB .... msPartX though this feels awkward. The most obvious issue is that the PartA, ..., PartX are distracting; unless of course I can find a natural way of splitting and naming them. Ideally, the parts should be as close to a comfortable line width as possible. Again, awkward. If myStruct1 and myStruct2 have the same partitioning scheme but myStruct2 (for instance) is much larger than myStruct1, there will be many sparsely, or many overpopulated lines. Awkward too. I love J. It handles complex regular data so elegantly. How can I bring similar elegance to irregular data? Can my combinators be rescued, or should I use another approach? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
