After a little more testing:

This.Label1.Caption = " =" && No error
This.Label1.Caption = "= " && Error
This.Label1.Caption = Chr(61) && Error

>This works fine in VFP7 (Except for the try-catch) The line This.Label1.Caption = "=" causes a Syntax error and is not catched by the try-catch. Looks like a compile time error.

>Can anyone confirm it's bug? Any workaround ?
