Formatted screen - hex mode

In three-line vertical HEX mode, one segment occurrence per screen and one field per set of three lines are displayed in the Formatted screen as shown in the following figure.

Formatted Screen - Hex Mode

The Formatted screen displays seven heading lines in three-line vertical HEX mode. The first four heading lines are identical to the Formatted Screen - Character mode. For more information, see here.

The fifth and sixth lines display the first 41 characters of the concatenated key with the upper and lower half-bytes of each character in HEX.

The seventh heading line, screen body consists of the following column headings:

• Level Number/Data-Name
• Format or Columns
• Field Value

The screen body displays the current segment in three-line vertical HEX mode. The top line of the HEX display represents the character format of the field value, the middle line represents the upper half-byte of each character in HEX, and the third line represents the lower half-byte of each character in HEX. To change segment contents, you can type over the character or HEX line. If you type over both the character and HEX lines for the same character, the character type over is ignored.

Level Number/Data-Name

The Level Number/Data-Name column displays the level number and data-name of each item in the segment layout.

Format

The Format column displays the format of each item (for COBOL, USAGE, and PICTURE information; for PL/I, attribute information). The COBOL and PL/I format information in the Formatted Screen - HEX mode is identical to the information that displays in Character mode. For more information, see Format. Note that the SHOW command (Formatted Screen - Format Mode) will replace the Format column with a Columns column as described below.

Columns

The Columns column (Formatted Screen - Columns Mode) displays the starting position of each data element displayed on the Formatted screen. Note that the SHOW command will replace the Columns column with the Format column described above.

Field Value

The Field Value column displays the value of each elementary item in the current segment. The field is blank and protected for lines with non-elementary items. It is also protected for key fields. To change the field value, type over the Field Value column.

In HEX mode, the field value shows actual internal data representation. Fields marked INVALD remain highlighted for the three-line display.

See Field Value for more information on alphanumeric and numeric field value display.
