The ∟ command indicates the beginning of a custom list (i.e., any list the user creates, not including the default lists L,,1,,...L,,6,,). You almost always need to include this when accessing or manipulating a custom list. The maximum length of the list name (not including the ∟) is five letters. ∟ABCDE works, but ∟ABCDEF does not.


You don't need to include the ∟ command when storing (→) to a list. Some of the list commands also allow for this optimization, such as SetUpEditor. However, it can create problems when using Input and Prompt because you might only be asking the user to input a list, but a real variable would also be allowed.

Error Conditions

  • ERR:UNDEFINED is thrown if you try to use ∟ on an undefined list.
