When pressed, the current file will be processed to extract all the relevant ASN code entries found in it, and these will be gathered into a textual ASN source file for further use. The final file will be named as per the file name provided to the right. Any prior file by that name will be deleted. Typically a proper ASN header section is then added and the source file is processed by a complier. You can achieve the same results using the Export1 button in the Mini-Edit tool.
