Questions about dlgstring dialog

I have file C:\New folder\New file.pdf
I have button {dlgstring|{filepath$|noext}_suffix.txt} to display C:\New folder\New file_suffix.txt as in dlgstring.


Questions:

  • \N from path are converted to line-breaks. How I can escape it ?
  • _suffix.txt is display in field. Why in field ?

If I want to display C:\New folder\New file_suffix.txt in field, I have this button {dlgstring||{filepath$|noext}_suffix.txt}


Question:

  • where is "_suffix.txt" in field ?

Oups, I post the wrong screenshot...
_suffix.txt is display in field in 1st screenshot (no & and no quotes).

Things that needed adding in bold:
