[GTVDEF\]WRITE
WRITE writes terminal parameters from the local parameter table to the
current Binary Terminal Definition File (BTDF, see USE).
Current primary and secondary terminal names are used (see NAME1 and
NAME2), and checked against any ambiguity with existing terminal names
in the BTDF file. If the terminal name is already present, its defini-
tion is updated.
The total number of terminal definitions in a BTDF is limited by the NT-
MX built-in parameter (currently 32).
