## General Settings - Compiler Variables |

| On this tab of the General Settings step you enter compiler variables for your project. Defining compiler variables is optional and not required for a working project. For an explanation of compiler variables, please see the help topic on variables.

| The control buttons on the right allow you to modify the contents of the compiler variables list: Add variable (key `INS`) Adds a new variable. The variable name must be unique and must not be the name of a system variable. Remove variable (key `DEL`) Removes the currently selected variable. Move variable up (key `ALT-UP`) Moves the selected variable up one position in the variables list. Move variable down (key `ALT-DOWN`) Moves the selected variable down one position in the variables list. In order to edit any column, please double-click on it.
