MapInfo Tab Name Length limis 30 is character limit. You can create a longer tab file name and it will use it, but it will be truncated wherever its used.(Layer control, Table List, dialogs, etc.). The true limit is (MAX_LENGTH).
Internally MI Pro uses a fixed character limit for all table "aliases" This is the name that is used to identify a table and it must be unique in any Pro session.
