Use the Hex Editor

The hex editor displays offsets, hexadecimal bytes, and EBCDIC or ASCII text. OL-CICS and CTG use it to prepare fixed-size commarea buffers.

Edit safely

Select EBCDIC or ASCII and the needed code page. Click the text section to overwrite characters; the hex representation updates automatically. The editor is overwrite-only, so inserts and deletions are not allowed.

Controls

• Reset: reset to 256 00 bytes, or EBCDIC blanks (40) when Fill blanks is enabled
• Set buffer size: truncate or extend using the selected fill byte
• Import: load raw .bin, .data, or .dat bytes
• Export: download current raw bytes as export.bin

Use import/export to reuse controlled test data. Validate buffer sizes and encodings before sending a transaction.
