Sample Usage
As an example, the following function
call:
list="{lst(1 'a' 'A' 3.14159)}"
element_value="lst_pick(list;4)"returns the
value found at index position 4 in list. In this case, the value is an
approximation of pi.Example: Get the value of element at the I'th position
Once a list-value is created, values at any index position can be retrieved using the
lst_pick(L;I)
function.
<base table="default.lonely"/> <let list="{lst(',not,a,moon,'',a,spacestation!')}" not="1" is="2"> <foreach x="That\'s {lst_pick({@list};{@not})} It\'s{lst_pick({@list};{@is})}" tally_="@i"> <willbe name="x{@i}" value="'{@x}'"/> </foreach> </let> <colord hide="c1"/>
The code above returns a series of computed columns where each word in the phrase
That's not a moon, it's a spacestation! is contained in its own
column.
