Increment and decrement operations Increment and decrement operations
These two operators work only on numeric operands. The syntax is: <target>++ <target>-- ++ increments <target> by one, -- decrements <target> by one. These are equivalent to += 1 and -= 1. <target> must be an existing variable and contain an integer value. If <target> contains a real value then the real is truncated to the nearest integer and then incremented or decremented.
Examples
%a=10 echo "Incrementing" while(%a < 20) { echo %a %a++ } echo "Decrementing" while(%a > 10) { echo %a %a-- } echo "Testing for loop" for(%a=0;%a < 10;%a++) { echo %a }
