! Dan Szymanski, 21-JUL-80, 01
! As part of the expanded key definition facilities, the default
! definitions for VT52 and VT100 keypads have been moved to KEYPAD.
! The table TRN_TBL now contains (relative) pointers to the strings
! of nokeypad commands defining the keys. The variable TRN_TBLINIT was
! added to indicate the initialization of the translation table.
