Those line show different "areas" in COBOL code. There are more than 3 areas, but these three are good to know:
Indicator Area
Area A
Area B

Basically, those vertical lines tell you which column some things need to start. For example, an asterisk in the Indicator Area makes the line comment, and a dash in the Indicator Area continues a long line of code. Section names begin in Area A. The code within a section begins in Area B. You probably wouldn't want to "turn off" these lines for COBOL development.
