@RANDOM[min, max]:  Returns a pseudo random integer value between min and max, inclusive. The random number generator is initialized from the system clock the first time it is used after TCC starts and will therefore produce a different sequence of numbers each time you use it. Min and max are 32-bit signed integers, so the allowable range is -2,147,483,647 to 2,147,483,647.

 

Examples:

 

echo %@random[0,1]

0

 

echo %@random[-10,10]

7

 

echo %@random[-10,10]

9

 

echo %@random[-10,10]
