From article <66253@lanl.gov>, by jlg@lanl.gov (Jim Giles): > ... There are _NO_ pointers in > the source code for TeX 'packed array tries'. The code does everything > through the use of Pascal arrays. For theoretical considerations, an index into an array is not much different from a pointer is it? Range-checking is the only significant difference I can think of, and that only makes incorrect programs fail nicer. (Pointers also have some measure of range-checking, "segmentation violation" for example. Never happened to *me* of course, but I've heard rumors.)
