[netrexx-pipelines] Indexed strings with multiple indices and the exists() method

[J L. T. <jlt...@ma...>]

Hi,
	Say I want to use an indexed string with two levels of indices:
| list[level1,level2]
Can I use
| list.exists(index)
to test just the first level?  Or would it be
| list.exists(index,)
?
