Dec

Dec VariableToDecrease, [ OptionalAmount ]

Parameters:     VariableToDecrease = The integer or floating point variable you wish to subtract one from.     [ OptionalAmount ] = The amount to subtract from this variable. If not provided this defaults to 1

Returns: NONE

The Dec command gives us an easier way to subtract one from integer or float variables. FACTS:       * Dec only works with Integer and Floating point variables.       * Dec is shorthand for the expression Variable=Variable-1       * The Dec does Not work with Arrays or Types.       * Note: PlayBASIC also support various math short Operators, such as -- , and -= which perform the same operation as Dec, but can be used upon any data type. Mini Tutorial: Set a variable to a value, dec it and display the effect.    ; create integer variable called Counter and assign it starting value of ten   Counter=10    ; Display the value of the counter variable   Print Counter    ; Subtract one from the counter variable.   Dec Counter    ; Display the value of the counter variable   Print Counter       ; Subtract five from the counter variable.   Dec Counter, 5    ; Display the value of the counter variable   Print Counter       ; Show Screen and wait for input to end   Sync   WaitKey       This example will output      10   9   4
