How to decode sequence.S files in ChemStation?

Question

Hi 
 
 Many of the files in Chemstation and Mass Hunter are txt or XML files. These are easy to open and edit to generate or process data using any computational language. 
 
 However, the sequence file (*.S) in Open Lab CDS Chemstation seems to be a binary file. I tried to decode it, and I can partially read it, but not completely. 
 
 Is there any information on how to decode this file? 
 
 thanks

If anyone is interested, I managed to extract the file data from binary files .S in batch. 
 
 In short, lets create a sample sequence and save it as sequence.S to use as example:

Then read the content in hexadecimal:

Then just filter the data:

Look for patterns, confirm with several .S files the patterns, and all the information can be automatized for batch files. Go the opposite way to reconstruct .S files (Oly modify hexa data).
