The C128 ReturnType is an optional property used with IDAutomation’s barcode font encoders to add additional functionality to the information returned from a function.
| ReturnType | Specification Description | Example |
| 0 | Returns a character string formatted to the associated barcode font. When this text is used with the appropriate font, a proper barcode will be created. |  |
| 1 | Returns a text string for a standard font such as Arial. Usually used to display the human-readable text for GS1-128 with the C128() function. | (17) 231231 |
| 2 | Returns the check digit only, if applicable. | 3 |
| Types 3 to 5 return a human-readable text interpretation in the same manner as the SpliceText function with Font Encoders that are Feature Level 10 or greater using the Code128() function. | ||
| ReturnType | Specification Description | Example |
| 3 | Returns human-readable text spliced every 3 digits, if applicable. | 172 312 310 |
| 4 | Returns human-readable text spliced every 4 digits, if applicable. | 1723 1231 0 |
| 5 | Returns human-readable text spliced every 5 digits, if applicable. | 17231 2310 |
| 6 – 9 | NOTE: There have been problems using ReturnTypes 6 – 9 in some versions of Windows 10 and greater, therefore, these are no longer guaranteed to work. Instead, it is recommended to place a field below the barcode with the text data. |  |
Options for HIBC:
| ReturnType | Specification Description | Example |
