Manolo N.J. Posts: 1 Rating: (0)	El Problema está en la instrucción "DO DW121" deberias chequear el programa original en Step 5 y asegurarte de que esa instrucción es correcta.

El Problema está en la instrucción "DO DW121" deberias chequear el programa original en Step 5 y asegurarte de que esa instrucción es correcta. Translation from the Spanish: Manolo N.J. The problem is in the instruction"DO DW121". You should chek the originalStep 5 program and make sure this instruction is correct. Hola Manolo; Gracias por tu respuesta, pero si es posible de responder en ingles, seria muy apreciado. El ingles es el idioma escogido para esta seccion del foro, la seccion internacional. La otra seccion usa el aleman. Thank you for your answer, but if it is possible could you please reply in Englsh, we would appeciate it. English has been chosen as the language of the international section of the forum. The other section uses German. Hope this helps, Daniel Chartier
