Thanks so much for the reply! Yes my first time with binary fields, I did not think it would be difficult since I had found great examples with COMP -3 fields on this site but I haven't had much luck with mapping these yet

Here is the hexdump of my input file...fixed length of 34 bytes. Please so let me know if my hexdump is not what you need. I am relatively new to hexdump so this might not be what you want.

hexdump -c -n 34 sltywk_binary_new
