After executing a command POICMD returns a value to its caller. This return value can be used in batch files (e.g. *.cmd or *.bat). You can use the %errorlevel% environment variable in order to retrieve the return value. For example if you call "poicmd" without parameters the return value will be 2.
Here is a complete list of all possible return values:
| Value | Meaning |
| 0 | POICMD successfully executed (and parameters where specified) |
| 1 | There where parameters but nothing to do (e.g. poicmd /help) |
| 2 | No parameter was specified. This is just a 'warning'. |
| 4 | You have specified an unknown parameter. |
| 5 - 9 | Not used. |
| 10 | The specified file could not be found. |
| 11 | The specified file already exists. |
| 12 - 19 | Not used. |
| 20 | You have specified an invalid number of command values. |
| 21 | An command parameter value has an invalid value (e.g. /lat:4801xy) |
| 22 - 98 | Not used. |
| 99 | Unspecified error. Look at the error message which gives you some information about the problem. |
