How to define the rotation by single step value?

Hi.

I want to  rotate  the componet by incremetal values of 1,2,3,4,5,... etc in degree incremental values. So i had to tried incremental values. But the component can't able to rotate the manual values entered by us. 

Then while doing the rotation default angles are be get rotated. Then i had tried to change the values in pcb env env. editor too.

While opening the editor the line getting error message.
