Anexo C, Códigos de error de 4D Internet Commands
Todos 4D Internet Commands (con excepción de IT_ErrorText y IT_Version) devuelven un valor entero como resultado. Este entero contiene un número de error que el comando debe devolver a la base de datos 4D. Si un comando se ejecuta correctamente, devuelve cero.
El origen de un error puede generalmente determinarse a partir del rango de valores en el que se sitúa su número. La siguiente tabla ofrece un índice a las principales fuentes de error en función de su número:
| Número de error | Generado por |
| Error < 0 | Sistema operativo o capa de red WinSock |
| 0 | Sin error |
| Error 1 -> 61 | capa de red BSD |
| Error >= 10000 | 4D Internet Commands |
Si un error se produce durante la ejecución de un comando Internet de 4D, se devuelve uno de los siguientes valores:
| 10000 | user cancelled a dialog or progress. |

Los siguientes valores no son códigos de error devueltos por los comandos Internet de 4D.

Esta lista es particularmente útil cuando crea su propio sistema de mensajería con la ayuda de los comandos TCP de bajo nivel.
