Description
The add to table instruction adds word values DATA to a table TBL. The first value in
the table is the maximum table length TL. The second value is the entry count EC,
which stores the number of entries in the table and is updated automatically. New data
are added to the table after the last entry. Each time new data are added to the table,
the entry count is incremented.
A table can have up to 100 data entries.
