Dec Command

Purpose

Decrements a numeric variable.

Syntax

Dec x

Description

Dec x decrements the value of x by 1.

Example

OpenW # 1

Local x = 2.7

Dec x

Print // Prints 1.7

Remarks

Although Dec can be used with any numeric variable, the usage of integer variables is recommended in order to achieve the maximum optimisation for speed.

Instead of Dec

x = x - 1

x := x - 1

x -= 1

x--

Sub x, 1

Add x, -1

can be used instead.

When integer variables are used Dec doesn't test for overflow!
