The following example shows how a clause is composed of tokens:

This example is composed of six tokens—a literal string ("REPEAT"), a blank operator, a symbol (A, which can have an assigned value), an operator (+), a second symbol (3, which is a number and a symbol), and the clause delimiter (;). The blanks between the A and the + and between the + and the 3 are removed. However, one of the blanks between the "REPEAT" and the A remains as an operator. Thus, this clause is treated as though written:

"REPEAT" A+3;
