PA_Fr<n> will normally be one character long. If there are more characters in this sequence then the first character is replaced by the translation string, but the others are printed as well.

In addition to the Panel and Printer Editor, the following parameters can be set. They expect HL to point to a null-terminated string: 

SP_Dev ($8C00)                Set current device
SP_Dir ($8C03)                Set current directory
                              Note: Use always a '/' in front of the path name,
                              otherwise OS_Nq can crash when reading the
                              parameter.
SP_Fnm ($8C06)                Set current name match
