I wouldn't ignore arrays, but I have been considering substructure in strings. MC stings are byte strings and it might be that same-size char chunk replacements are efficient. If so, you can create a data space within a string in a global variable. I'd run the experiment, anyway. Or you might try a mix in which some data are packed in strings and others are not, in which some pointers are implemented as arrays and some are implemented as string offsets. This might be better if strings are always rebuilt. Dar Scott ___ metacard mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/metacard

Im looking for tips regarding porting variable redirection (pointers and pointers to pointers) and c-style struct variables. The key to porting these is speed as NN require speed and ease of scripting as MC is all about that! for example: how do you port x[a][b] = item b of line a of x But this proves extremely slow once you reach a1000... what about p-x-b[i] so far the best I found (without much searching I admit) is p_x_b[i] but what of p-x[a]-b Im looking for any good schemes you may propose! Thanks in advance for any help!
