- NB.
- NB. I find that in for statments it is often useful to have
- NB. access to the interation index, but I haven't found
- NB. how to access it. So have cooked up the following
- NB. example to illustrate my point. One third of the
- NB. time the verb h returns y. appended with half of the
- NB. tail of y. , one third of the time y. with double of the
- NB. tail of y. appended, and one third of the time it returns
- NB. y. with 1000 times the interation index appended.
- NB. Unfortunately, and not suprisingly, my attempt below
- NB. yeilds a value error since $. is only implicitly assigned
- NB. to i. ns . I can easily imagine that one can not access the
- NB. interation index but perhaps someone else has some ideas,
- NB. like on how to assign and access $. ?
