GetLayer()
Summary
Gets the name of the current layer, if any.
Syntax
layer_name = GetLayer()
Returns
A string indicating the name of the current layer, or null if there is no current layer.
Notes
-
Any function that accepts a layer name as an argument uses the current layer if the argument is left null.
-
Each map has its own current layer. There are times when no current layer has been set. In that case, GetLayer() returns null.
Example
lyr = GetLayer()
