MapInfo Professional: Does MapInfo Pro support TAB files created outside of it.

MapInfo Pro native format (often referred to as TAB) supports a maximum width of 20 in decimal fields.

The width can range from 1 to 20, and the number of decimal places can range from 0 to 16. The number of decimal places setting must be at least 2 less than the width (or zero).

MapInfo Pro does not support native (TAB) tables created by other products because the other products don't always respect these documented limits.
