I have seen a number of posts here and elsewhere indicating that LOR files are an XML format and implying that LSP is not.
That is quite to the contrary. If you download 7-zip (must use 7-zip) you can then unzip any MSQ or ASQ file and you will see that it is indeed XML.
Warning Will Robinson Warning......... make changes to to this file at your own risk. It is also important to note that you can only unzip it if it is under your license limit.
I fully suspect that no support will be given to an issues caused by changing this file outside of LSP.
