The Pathname field displays the path name of the selected file. The Type field display the file type for the selected file.

The format and tag information for the file can be changed by updating these input fields on the panel:

Format

Enter one of the listed numbers corresponding to one of these formats required for the file:

NA: No format specified.
Binary: Binary data.
NL: Text file; lines delimited by the newline character.
CR: Text file; lines delimited by the carriage-return character.
LF: Text file; lines delimited by the line-feed character.
CRLF: Text file; lines delimited by carriage-return and line-feed characters.
LFCR: Text file; lines delimited by line-feed and carriage-return characters.
CRNL: Text file; lines delimited by carriage-return and newline characters.

CCSID

Enter the numeric coded character set identifier (CCSID) associated with the file. The numeric value must be between 0 and 65535. You can set this field to blanks or enter a value of 0 to indicate there is no CCSID associated with the file.

Automatic Conversion

Select this option to identify the file as a candidate for automatic conversion provided by z/OS UNIX Enhanced ASCII support.

Note:

A superuser or the owner can change the file format of a file.
A superuser, the owner, or a user with write permission can change the tag information (CCSID and automatic conversion setting) for a file.
File tag information cannot be set for a z/OS UNIX directory. Therefore when processing a directory the CCSID and Automatic Conversion fields are protected.
