SIMPOL Documentation

In addition to intrinsic functions there are operators which work on one or more parameters. Common examples of these are the addition operator +, the unary negation operator - which converts a value to its opposite, in some sense depending on the value type, and the comparison operators, ==, < etc., which return a boolean value that depends on a comparison between the left and right operands. It should be noted that operators operate on values, not objects. For example the code:

integer i
integer j
i = 3
j = - i

does not change the value in the object referred to by i from 3, it takes the value from that object, negates the value only, and assigns the result to j.
