Tab
Tab and indent size
Defines the number of spaces inserted when you press Tab or Enter. When programming in COBOL, the Compiler expects the meaningful code to start from column eight. This is why it is convenient to have the tab character replaced by four spaces to reduce the risk of introducing compilation errors in the code.
Insert spaces
Replaces the tab character with the number of spaces specified in the Tab and indent size field.
Keep tabs
Inserts a tab character when you press Tab.
