IDL CODA reading L1b Sciamachy files

I recently downloaded an IDL CODA procedure to read the SCIAMACHY Level 1b files. I recall that there were many other readers available including a L2 reader, which I now need. But
I can’t find the web page where I obtained the L1b reader. Can you point me to that location?
Thankyou

Do you mean the CODA IDL examples?
