If you know which 8-bit characters your data contains and you can locate them in the table dump (.d) file, examine the numeric values of the data bytes in the file. You can do this with any hexadecimal dump program provided by your operating system or with a OpenEdge ABL program that has the following syntax:

INPUT FROM filename NO-MAP.
REPEAT:
  READKEY.
  DISPLAY LASTKEY.
END.
filename
The name of your file.
Note: Start OpenEdge with -cpinternal set to undefined.
