-++ accessed one byte at a time as a small integer.

- Cat == FileCategory(FileName, SingleInteger) with
- readIfCan_!: % -> Union(SingleInteger, "failed")
- ++ readIfCan!(f) returns a value from the file f, if possible.
- ++ If f is not open for reading, or if f is at the end of file
- ++ then \spad{"failed"} is the result.
-
--- "#": % -> SingleInteger
--- ++ #(f) returns the length of the file f in bytes.
-
- position: % -> SingleInteger
- ++ position(f) returns the current byte-position in the file f.
-
- position_!: (%, SingleInteger) -> SingleInteger
- ++ position!(f, i) sets the current byte-position to i.
