Variables are objects that hold values. Variables refer to integer, real, string, or point operands. Variables are essential to using expressions. A variable has a name and a value. The name is used to access the value of the variable. The name is constant; the value can be changed. You can use the ASSIGN/ command to assign a value to a variable.
For example, the statement ASSIGN/V1=2 creates a variable with a name of V1 and a value of 2. ASSIGN/V2=V1+2 accesses the value of V1. If V1 still had a value of 2 when this assign statement was executed, V2 would then have a value of 4.
