Decode or reverse engineer this old file structure

I have a need to create some files to be able to be sent to a device. The software that created these is no longer made. They are 654 byte of data which takes up 4k of space on the drive. These files are transferred via modem and are loaded into a machine: they contain 12 fields: Last name (16 spaces) , first name (10 spaces), ID number (12 spaces) Age 3 spaces of 5 selections - years months weeks, days hours, Gender 0/1 Race(12 spaces), Height weight Order number (9 spaces)Type - ECG,PED, GXT, MXT I need to deconstruct the file format and have a piece of software written that would allow me to write these files from an XML file. I'd like to be able to drop and XML file in one directory and one of these [login to view URL] files pop out the other end. In order to verify - I would need the FL to be able to create a file and send it to me and I should be able to open it up and read on my device. The attached files were created on the device. I'm not sure if there is any compression or not, I dont think so. I can open it up in a hex editor and see the text. Milestones: 1. download the files, and create a file I can read. For this I pay 50%. You will know whether or not you succeeded. Send me the file, I upload it if it works then I pay the first 50% 2. Write a small program that will allow me to drop in an XML file in a directory and the application will poll for new files every second and process into one of the [login to view URL] files. I pay the next 50% for that.
