ListConcat ( LIST1, LIST2 )
Finds the index of a value in a list.
Parameters
| Parameter | Type | Description |
|---|---|---|
| LIST1 | VALUE(LIST) | The first list. |
| LIST2 | VALUE(LIST) | The second list. |
Returns
| VALUE(LIST) | A new list. |
What It Does
This function takes two lists and concatenates them together into a new list, such that the resulting list contains the elements from the first list and then the elements from the second one. If either value is not a list, it is converted to a list with one element before concatenation (see AsList()).

textln(list);

while (x <= length(list))
{

// Add
ret = listAdd(list, 6); // list = [1, 2, 3, 4, 5, 6], returns true
textln(list + ": " + ret);
ret = listAdd(list, "apple"); // list = [1, 2, 3, 4, 5, 6, "apple"], returns true
textln(list + ": " + ret);
// AddAt
ret = listAddAt(list, 7, 2); // list = [1, 2, 7, 3, 4, 5, 6, "apple", "banana"], returns true
textln(list + ": " + ret);
ret = listAddAt(list, "banana", 10); // list = [1, 2, 7, 3, 4, 5, 6, "apple", "banana"], returns true
textln(list + ": " + ret);
// Remove
ret = listRemove(list, 3); // list = [1, 2, 7, 4, 5, 6, "apple", "banana"], returns true
textln(list + ": " + ret);
ret = listRemove(list, 100); // list = [1, 2, 7, 4, 5, 6, "apple", "banana"], returns false
textln(list + ": " + ret);
// RemoveAt
ret = listRemoveAt(list, 0); // list = [2, 7, 4, 5, 6, "apple", "banana"], returns 1
textln(list + ": " + ret);
ret = listRemoveAt(list, 50); // list = [2, 7, 4, 5, 6, "apple", "banana"], returns false
textln(list + ": " + ret);
// Index
textln(listIndex(list, 4)); // 2
textln(listIndex(list, 1)); // -1
textln(listIndex(list, "4")); // -1
// Contains
textln(listContains(list, 4)); // true
textln(listContains(list, 1)); // false
textln(listContains(list, "4")); // false
// Concatenation
textln(listConcat([1, 2, 3], [4, 5, 6])); // [1, 2, 3, 4, 5, 6]
textln(listConcat([1, 2, 3], 4)); // [1, 2, 3, 4]
textln(listConcat("apple", "orange")); // ["apple", "orange"]
