INC VAR

 Function
  Increment the value of a variable specified by VAR.

 Syntax
  INC var

   var  - The variable with the value to increment

 Remarks
  Many programs require extensive addition and subtraction, and most
  often, a value is increased or decreased by 1.  This statement allows for
  a shorter, more efficient method of increasing (incrementing) a value
  by 1 than adding 1 to a variable and assigning the result to the same
  variable.

 Examples
  INTEGER i
  PRINTLN "Countdown:"
  LET i = 0
  WHILE (i <= 10) DO
   PRINTLN "T plus ",i
   INC i
  ENDWHILE
