Logical Operators

• arity: 2
• incptr: 0

In zrpc, logical operators are functions, and so they have the same properties as normal built-in functions. Each logical operator has an arity of 2 and an incptr of 0.

?{

Equivalent to "if (num1 == num2) {" in C, where both objects popped off the stack are numeric.

Usage:

1 1 ?{
    "equal numbers" printstr q
}

All logical operators work the same way, and there are no "and" or "or" operators.

!?{

Equivalent to "if (num1 != num2) {" in C.

Usage:

1 2 !?{
    "unequal numbers" printstr q
}

<?{

Usage:

1 2 <?{
    "1 is less than 2" printstr q
}

>?{

Usage:

2 1 >?{
    "2 is greater than 1" printstr q
}
