Volany,
Please be aware that Gentran does NOT add the HEX 1A to the inbound file. In fact unless you have delivery rules to "massage" the file Gentran there are no modifications to the file. If you would like to confrim this, then you can turn tracing on for your communications mailbox, which will log all characters sent/received in the communications log. You will see that the 0x1A is sent from the Van before it is written to the .atm file.
