Literature about QuickBasic

[Kernelpanic]

@Terry -  I didn't know QuickBasic supported line continuation (the underscore _ character).

The text in the QuickBasic 4.5 manual says the following: In the QB4.5 editor a line can only be 256 characters long; the editor does not recognize (accept) an underscore to continue the line.
It's different when using another editor. In this case, the underscore is removed at compile time and the continued lines are merged into one line. In this case, the line length limit is lifted.

Underscores are not continued in DATA and REM statements under any circumstances.
