System Parameters
'FN' Filename As-Is: No Case Conversion
 
Description On. Passes filenames to the OS with no case conversion.
Off. Case conversion is governed by the current setting of either 'FL' (Forces Lower
Case) or 'FU' (Forces Upper Case).
 
Default On, unless 'FL' or 'FU' are on. The 'FN' setting is not displayed in the list returned using PRINT PRM.
 
See Also 'FL' System Parameter, 'FU' System Parameter, and the FFN( ) Function (for a UNIX example using these parameters for case-insensitive searches).
