Command Result Codes

Top  Previous  Next

 

Each Robo-FTP script command returns a four-digit numeric result code when it completes to indicate success or failure. When Robo-FTP is used interactively, or if you need to interpret a log file, it is not necessary to know the specific numeric values because Robo-FTP translates all of these values to English phrases in the form of status messages. When writing these messages to the log file, Robo-FTP includes the numeric value in brackets at the end of the message to assist you in building error recovery into your script files.

 

When writing a script file you may want to take advantage of the IFERROR command to test for specific result codes. In this case, use these numeric values, or the corresponding predefined $ERROR_xxx variable (see below), in the IFERROR command to test for a specific result.

 

Robo-FTP always returns a zero result code if a script command is completed successfully. Therefore a script file checks for a non-zero result code to determine if an operation failed. If you choose to check for specific result codes when a command fails, you have more flexibility in recovering from errors.

 

Robo-FTP defines a set of internal variables referred to as $ERROR constants. $ERROR constants allow you to use descriptive variable names rather than a raw numeric result code value when using the IFERROR command. This results in easier to understand script files.

 

The Robo-FTP $ERROR constants and corresponding numeric result codes are listed below:
