CFN Display Format of File Names
CFN | NCFN Complete Filename. The names of the files and Job variables are displayed in the file list in a full, FSTAT compatible form. This means that the catid and userid of the files are always displayed. The system administrator can set the default CFN mode in the CFSMAIN module.
NCFN No Complete Filename. The standard format for displaying file names in CFS is used. The catid and userid of a file is only displayed if it is necessary to distinguish the file from another already in the list.
