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 }
