* Warning: many of these routines are MACROs for performance reasons
* - be carful where you use them. Don't use more than one per
* assignment statement -
* (eg itemLen += BEncEoc (b) + BEncFoo (b) ..; this
* will break the code)

* Revision 1.2 1995/07/27 08:42:40 rj
* cpp macro TBL changed to TTBL since some type table code uses TBL as a type name.
*
* changed `_' to `-' in file names.
