I am having problem to open idf file created by v9.0 by IDF editor for v9.0. I got error message as below.
I tried to investigate the reason opening in texteditor but could not find reason.
Could anyone tell me how I can try to solve this problem?
I also added part of the idf file content where having problem. image description

I think there is a larger issue at play here. Of this long list of Sub Surfaces, only two actually belong to 1212-Office-TZ (I am the one who wrote this file). This is correctly reflected in the OpenStudio interface and in the geometry portions of the .idf, but for some reason gets messed up in the WindowShadingControl portion.

Then it sounds like this is an OpenStudio question. It may be that OS is taking a shortcut and writing a single WindowShadingControl object instead of one per zone. Do all of these subsurfaces have the same shading control rule? Well, in this case, I guess they do because it's no shading. In the new WindowShadingControl object, the zone name is important from a control aspect especially if the shading control if for daylighting or glare. But the surface list doesn't necessarily have to all be from that same zone.

IDF Editor works off the object definitions in the EnergyPlus IDD file, energy+.idd located in the root EnergyPlus install folder, C:\EnergyPlusV9-0-1 for example. For this particular case, the idd definition stops at 10 surfaces. To fix this, you have two options:

Edit the idf file and split the WindowShadingControl object into multiple instances which have 10 or less surfaces each, just be sure to give each one a unique name.
Edit energy+.idd to extend this object.

The existing idd definition ends like this:

WindowShadingControl,
   \memo Specifies the type, location, and controls for window shades, window blinds, and
   \memo switchable glazing. Referencing the surface objects for exterior windows and glass
   \memo doors (ref: FenestrationSurface:Detailed, Window, and GlazedDoor).
   \extensible:1
A1 , \field Name
   \required-field
<snip>
A22, \field Fenestration Surface 9 Name
   \type object-list
   \object-list GlazedExtSubSurfNames
   \note When Multiple Surface Control Type is set to Sequential the shades will be deployed for the referenced surface objects in order. 
   \note When that field is set to Group the entire list is controlled simultaneously.
A23; \field Fenestration Surface 10 Name
   \type object-list
   \object-list GlazedExtSubSurfNames
   \note When Multiple Surface Control Type is set to Sequential the shades will be deployed for the referenced surface objects in order. 
   \note When that field is set to Group the entire list is controlled simultaneously.

If you don't plan to edit these, just add bunch of lines before the last entry to extend the object and then renumber that final one.

A23, \field Fenestration Surface Name
A24, \field Fenestration Surface Name
A25, \field Fenestration Surface Name
A26, \field Fenestration Surface Name
<etc.>
A102, \field Fenestration Surface Name
A103; \field Fenestration Surface Name
   \type object-list
   \object-list GlazedExtSubSurfNames
   \note When Multiple Surface Control Type is set to Sequential the shades will be deployed for the referenced surface objects in order. 
   \note When that field is set to Group the entire list is controlled simultaneously.
