Double-byte character set support

z/OS ISPF Edit and Edit Macros
SC19-3621-00

The ISPF editor supports DBCS alphabets in two ways:

  • Formatted data where DBCS characters are in the column positions specified in the format definition created with the Format Utility (option 3.11)
  • Mixed characters delimited with the special shift-out and shift-in characters.

    If you are using mixed mode and the record length of a data set is greater than 72 bytes, there is a possibility that a DBCS character might encroach on the display boundary. Here, PDF attempts to display the other characters by replacing an unpaired DBCS character byte with an SO or SI character. If there is a possibility that the replaced SO or SI character was erased, the line number of the line is highlighted. If you change the position of the SO and SI characters on the panel, or if you delete the SO and SI characters entirely, the DBCS character on the boundary is removed to keep the rest of the data intact.
