Basic Programming Concepts While a belt variable can be used as the first (leftmost) element of a compound transformation to define a transformation value, a belt variable cannot appear by itself. For example, LISTL will not display a belt variable directly. To view the value of a belt variable, enter the command: LISTL %belt_variable:NULL 1 Before defining a location relative to a belt, you must make sure the belt encoder offset is set properly. That usually involves issuing a monitor command in the form: DO SETBELT %belt = BELT(%belt) eV+Language User's Guide, v2.x, 18318-000 Rev A Page 198
