The Hex/EBCDIC editing mode works almost identically to the Hex Editing mode with the exception it will convert the EBCDIC data for viewing purposes only and show this as ASCII. The content of the file will not be modified, however the right hand side that shows the ASCII representation in Hex Mode will show the data converted to ASCII from EBCDIC.
For details of editing in Hex mode, see Hex Edit command.
While in this mode, editing in the ASCII area will allow data to be entered as ASCII and automatically converted to EBCDIC in the file. Editing in the Hex area will allow data to be entered directly as Hex and the ASCII representation (converted from EBCDIC) will be shown in the ASCII area.
Find/Replace in this mode will allow ASCII strings to be used and correctly found/replaced according to the settings in the Find/Replace dialog box. Regular Expressions however cannot be used in this mode, the results would be indeterminate.
