I vaguely remember that thematic map layer names look like array
elements, but actually must be enclosed in double quotes when referenced
in a string. That is, if your parent layer is named 'markets' then your
first thematic layer is called "markets(1)", and the double quotes are
important. You might check the docs on that to be sure, but I think
you'll have to test to see if a layer is thematic and if so, wrap it in
quotes inside your command string.
As an aside, I also know that if you separate the thematic layer from
its parent using the 'set map order' statement, and then go into Layer
Control interactively, you'l crash MapInfo good and hard.

I am having some trouble with ordering layers in a mapper window using MapBasic.
I have some layers that are added to a mapper by pushing a tool button in
MapInfo. The button adds the layers, and then puts them to the bottom layer of
the mapper window as they are base mapping data.
The code I have written creates a string of the layers that are in the map
window, and then adds the layer i want at the bottom of the mapper window to
the end of this string. I then use Run Command to run this string. For example,
the code looks something like this:
---------------------------
layer = layer i want moved to bottom of mapper window
Dim tmpCmdStr As String
tmpCmdStr = "Set Map Order "
Dim i As Integer
For i = 1 To iNoLayers
If LayerInfo(FrontWindow(), i, LAYER_INFO_NAME) = layer Then
Else
tmpCmdStr = tmpCmdStr + LayerInfo(FrontWindow(), i, LAYER_INFO_NAME)+ ","
End If
Next
tmpCmdStr = tmpCmdStr + layer
Run Command tmpCmdStr
---------
This works fine until I encounter a thematic layer, and the set map order
command falls over complaining of Unrecognised Command ( , which is when i gets
to the thematic layer.
Does anyone have any idea as to why this is happening, and how it can be fixed.
