You'd have to modify the Get() procedure in get.e, to return the value
of the integer string_next. (Or maybe get_ch(). I dunno.)

Or, make the variable string_next global instead of local. Or add a new
function to return the value of string_next() (and, if reading from a file,
perhaps to return the value of where()).

Use sprint(), or get print.e (which makes a human-readable string, i.e.
{65, 66, 67} becomes "ABC").
