ilev()

ilev()
itext(\<n\>)
%i\<n\>
inum(\<n\>)

These functions return the equivilent of ## (itext) or #@ (inum) for iter() and @dolist, where an \<n\>=0 returns to the current iter or @dolist, \<n\>=1 refers to the iter()/@dolist which the current iter() or @dolist is nested in, etc. An \<n\> of “L” can be used to refer to the outermost iter()/@dolist. %i\<n\> is an alias for itext(\<n\>), where \<n\> can be from 0 to 9 (or “L”).

ilev() returns the current nesting depth, or -1 when used outside an iter() or @dolist. Thus, itext(ilev()) will return the outermost ##, equivilent to %iL.

Nested iteration examples

Examples:

say iter(red blue green, iter(fish shoe, #@:##))
You say, "1:red 1:red 2:blue 2:blue 3:green 3:green"

> say iter(red blue green, iter(fish shoe, inum(ilev()):[itext(1)]))
You say, "1:red 1:red 2:blue 2:blue 3:green 3:green"

> say iter(red blue green,iter(fish shoe, inum(0):[itext(0)]))
You say, "1:fish 2:shoe 1:fish 2:shoe 1:fish 2:shoe"

> say iter(red blue green,iter(fish shoe, %i1:%i0))
You say, "red:fish red:shoe blue:fish blue:shoe green:fish green:shoe"

> @dolist red blue green=say iter(fish shoe, %i1:%i0)
You say, "red:fish red:shoe"
You say, "blue:fish blue:shoe"
You say, "green:fish green:shoe"
