The HEXDSK command lists a file on a sector-by-sector basis no matter what type of file structure the file has. When it executes the HEXDSK command, DUMPALL ignores the file attributes for MAXRECSIZE and BLOCKSIZE. The listing of the file includes those areas of the file that are not normally accessible to programs, such as gaps between blocks and any part of a sector that includes the end-of-file (EOF) character that is past the actual EOF. The HEXDSK command lists a file both in hexadecimal format and in ASCII or EBCDIC. If the EXTMODE value of the file is ASCII, the second list is in ASCII; otherwise, the second list is in EBCDIC.

Syntax

── HEXDSK ─┬─<file title>──────┬─┬──────────────────────┬──────────────┤
           └─<long file title>─┘ ├─<record range list>──┤
                                 └─<skip specification>─┘

Explanation

HEXDSK <file title>

HEXDSK <long file title>

Lists the entire file in hexadecimal and EBCDIC formats.

<record range list>

Specifies a group of records to be processed. Refer to “Record Range List” later in this section for more information about <record range list>.

<skip specification>

Causes only the portion of the file specified by the record range list or skip specification to be listed. In this command, the record range list and skip specification refer to sectors instead of records. The first sector of a file is sector number 1. Refer to “Skip Specification” later in this section for more information about <skip specification>.

Example

The following example shows both the input to and the output from a HEXDSK command. The output is of sector 4 of the disk file MYFILE/TEST. DUMPALL writes the text in word-sized chunks in EBCDIC and then in hexadecimal.
