# Markers

Markers are objects that may be associated with Workbench resources. There are many uses of markers in the Workbench. The three main uses of markers in the Workbench are:

- Tasks
- Problems
- Bookmarks

Markers are shown in a marker view (Tasks, Problems or Bookmark view) or on the marker bar in the editor area.

The following sections give more detail on each of these marker types.

## Tasks

A task marker represents a work item. There are two kinds of tasks:

- Automatically-generated information associated with the resource
- User specified tasks that may or may not be associated with a resource

Both of these task types appear in the Tasks view.

## Problems

Problem markers represent invalid states and are categorized as follows..

- Errors: Error markers are often used to indicate the source location of syntax or compilation errors.
- Warnings: Warning markers indicate the source location of, for example, compilation warnings.
- Information: Information markers indicate the source location of information only tasks.

Problems are shown in the Problems view.

## Bookmarks

Bookmarks place an anchor either at a specific line in a resource or on the resource itself. They are shown in the Bookmarks view.
