Parameters
table-id:
number identifying the character table to define the combination character, from 1 to

Function
This command starts to define the combination of characters by specifying the region
and coordinates. The characters to combine in this region are registered using the
ALTB T command (page 21). The ALTB S sequence is terminated by the ALTB E
command. If the identical table number already exists, the existing character table is
replaced with the new character table.
