The PF2 (Reposition) key displays a window in which you can enter a new starting value for the file list. When you enter a file number, the Display Files list begins with that file.
The Display Files screen provides the following information for each file:
file number and file name;
date the file was loaded into the database;
highest ISN currently in use in the file and the highest ISN allowed in the file;
number of logical extents currently assigned: by Associator ( N ormal index; U pper index; A ddress converter) and D ata Storage. A maximum of five logical extents may be allocated to a file.
block padding factor percentage defined for the Associator and for Data Storage;
indicators as follows:
| A | ADAM option: A = ADAM ISN- or descriptor-selected file; N = non-ADAM file. | 
| C | coupled (C) or non-coupled (N) file. | 
| I | ISNs are reusable (I) or not (N). | 
| S | Data Storage blocks are reusable (S) or not (N). | 
| E | data files are ciphered/encrypted (E) or not (N). | 
| X | files are expanded (X) or normal (N). | 
| U | USERISN option: U = option is in effect for the file; N = option is not in effect. | 
percentage of allocated space currently used by the file in the Associator and in Data Storage.
The equivalent direct command is
DISPLAY FILE
When a valid file number is specified on the Database Report menu, the following Display File Layout information is displayed for that file:

The information for the file can be refreshed by pressing PF4.
You can display additional information about UES codes, coupling, LOB file/fields and space allocations by pressing ENTER.
The equivalent direct command is
DISPLAY FILE file-number
The Display File Layout screen displays the following information for the file:
the file number and name;
the number of records currently contained in the file;
ISN information: the highest ISN currently used in the file; the highest ISN planned for the file (see the ADALOD utility's MAXISN parameter); the lowest ISN that can be assigned to a record in the file (see the ADALOD utility's MINISN parameter); whether 3- or 4-byte ISNs are used for the file; and whether ISNs can be reused.
the total number of updates since the file was last loaded;
other file option settings: whether Data Storage space can be reused; whether the file was loaded with the ADAM option, the cipher option, the USERISN option; whether the file is physically coupled to another file; whether Data Storage extents can be on different device types; whether the file can be refreshed using the E1 command; whether the file permits the MAXISN setting to be increased.
the number of blocks allowed per Data Storage, upper index, and normal index extent;
the date and time the file was last loaded;
the maximum compressed record length permitted for the file (see the ADALOD utility's MAXRECL parameter);
the padding factor for the Associator and for Data Storage;
the highest index level currently active for the file;
the total number of blocks in the file that have been changed by updates since the file was last loaded;
the length of the owner ID for multiclient files.
whether universal encoding support (UES) is being used.
When universal encoding support (UES) is being used, pressing ENTER from the initial Display File Layout screen lists the current code values:
