!• $ begins a text or date variable.
!• # begins a numeric variable.
!• % begins a list variable.
!• @ begins a variable name for a marker location.

!Literals
!Literals are text or numeric constants.
!• A single quote begins and ends a text literal. For example:

!• Numerals 0–9 begin numeric literals.
!Numerals that include digits with an optional decimal point and leading sign are acceptable
!numeric literals. For example, –543.21. Numeric literals can also be expressed in scientific
!form. For example, 1.2E5.
