Number Comparisons in Batch Code

I'm having difficulty with number comparisons like <, >, and == in my Batch code. What Im doing is generating a random number and using that answer to do something, this is what I've written:

set rand=%random%
set rand=%rand:~1,1% 
If %rand%==9 goto nine
If %rand%>5 goto above 5
If %rand%>1 goto above 1
If %rand%==0 goto zero

And the code just closes when I run it. I tried putting space between the two objects being compared and the inequality but it still doesn't work.

Remember, this is Batch code on Windows.

For the if commands use these keys instead of the equal and greater than symbols:

EQU - equal
NEQ - not equal
LSS - less than
LEQ - less than or equal
GTR - greater than
GEQ - greater than or equal

But I would suggest using == instead of EQU. It is easier to type.

read HELP IF and then try this

if %rand% equ 9 goto nine
if %rand% gtr 5 goto above5
goto below5

note that the label names cannot contain blanks

as an additional bonus, read HELP SET and change the way you try to obtain the random 0 to 9 number into

set /a rand=%random% %% 10
