DEC

The DEC command is used to decrement (i.e. decrease) the value of a numeric variable by one. It is a quick and concise way to subtract 1 from the value contained in a variable. In place of variable, enter the name of the numeric variable you want to decrement.

The DEC command is actually a shorthand for the subtraction operation, as writing num=num-1. However, DEC is often preferred because of its more concise syntax and its specific decrement function. The DEC command can only be applied to numeric variables (integer).
