Should the method (optionally?) check that that the stem array didn't have any elements with tails not meeting the only-incrementing-integers rule? For example, if one has a.1="one" a.2="two" a.3="what about this?" a.0=2 a.0.1 = "something else" a.0.2 = "and this" would it work (create a 2-element array) but ignore a.3 and the extra a.0.n elements? Should there also be an option to drop either the whole original stem, or perhaps just the elements that ended up in the array? -- Jeremy Nicoll - my opinions are my own. _______________________________________________ Oorexx-devel mailing list Oorexx-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/oorexx-devel
