GetLayers()

Gets information on layers in the system and the current layer.

In Version 2018 added the optional array of types.

layer_array = GetLayers(opt array types)

Argument	Contents
types	An optional array of strings with one or more layer types

An array of three elements:

Element	Type	Contents
1	Array	An array of the names of layers in the system (strings)
2	Integer	The index of the current layer in the list of names
3	String	The name of the current layer

The array of types is an optional argument.
The array of types, if provided, restricts the layer types. For a description of the types, see IsLayer.
If no layers are present, the return value is null. If there is no current layer, the second array element is -1 and the third is null.

lyr_info = GetLayers()

if lyr_info[3] = null then SetLayer(lyr_info[1][1])

lyrs = GetLayers({"Point"})

ShowArray(lyrs[1])
