I enter my filepath as a text string in Surfer, and I get "***Math Text Error***". Why?

Older versions of Surfer (version 10 and prior) read all single backslashes (\) as part of math text instruction. Therefore, if you insert a file path as text into Surfer with single back slashes ("C:\temp\test.srf"), then Surfer will think this is math text instruction. However, since it isn’t in the correct math text instruction format, you get the error.

What you can do is either:

1. Use two backslashes instead of one ("C:\\temp\\test.srf"). This is the easiest method. When you do this, it will still look like a single slash in the actual text in Surfer 10 since the first backslash is ignored.
2. Use a forward slash instead of backslash ("C:/temp/test.srf")
3. Upgrade your version of Surfer. The text editor has been greatly improved in Surfer versions 11 and higher. It does not have this problem in the current version.
