The OpenEdge Hive

Hi, i need to execute a .jar and recover the messages, i`m using INPUT THROUGH to do this but i get a black window when i use it. Does anyone know how to use this command without the black window?

Example:

DEFINE VARIABLE cmd AS CHARACTER NO-UNDO.
DEFINE TEMP-TABLE temp
FIELD texto AS CHAR.

INPUT THROUGH VALUE("notepad") .

INPUT THROUGH VALUE(cmd).

EMPTY TEMP-TABLE temp.
REPEAT :
CREATE temp.
IMPORT UNFORMATTED temp.
END.

FOR EACH temp:
DISP temp.
END.
