Boolean Is Equal or Greater '=>', '=>='

The Boolean operator Is Equal or Greater compares two operands and returns TRUE (-1) if the first value is equal to greater than the second value, or returns FALSE (0), otherwise. Is Equal or Greater can be used in both variable and constant expressions. Example:

X := Y => Z

The above example compares the value of Y with the value of Z and sets X to either: TRUE (-1) if Y is equal to or greater than the value of Z, or FALSE (0) if Y is less than the value of Z.

This operator is often used in conditional expressions, such as in the following example.

IF (Y => 100)

Here, the Is Equal or Greater operator returns TRUE if Y is equal to or greater than 100.

Is Equal or Greater has an assignment form, =>=, that uses the variable to its left as both the first operand and the result destination. For example,

X =>= Y      'Short form of X := X => Y 

Here, X is compared with Y, and if X is equal to or greater than Y, X is set to TRUE (-1), otherwise X is set to FALSE (0). The assignment form of Is Equal or Greater may also be used within expressions for intermediate results; see Intermediate Assignments.
