Is there anybody knows how to use parameters %C, %F and %L when designating an external text editor in EAGLE's Option Menu? I just learned from Internet that %F means only if this parameter is added in the command line, like "C:\WINDOWS\system32\notepad.exe" "%F", the ULP or SCR file can be opened directly in notepad, otherwise a new empty notepad will pop up.
Is there any more suggestions for %F? and %C and %L? Could anybody here give me some examples for the usage of these parameters?
