I remember many years ago reading through the IBM 360 (Mainframe)
assembler code for the Fortran 66 H compiler to understand how the
Hollerith constants were parsed.
I suspect finding an "H" after an integer (and skipping that many
following characters) might be problematic for today's scanners. 
There is an excellent write up in Wikipedia.
