Running the example: 

1. Open a command window and type 'rotax' (return)
2. When the progam asks for the compound code enter AS19A2
3. Enter y to test for 2-fold axes as twin laws. 

The output is:

Rotax ends, output in rotax.out



To test for other operations answer n to the question 'Test 2-fold axes only (Y/N)? :'.
Then enter the angle, determinant and upper figure of merit that you'd like to use.
e.g. to search for a -6 operation with an upper figure of merit of 10 the entry would be 
60 -1 10
Foe a 6 fold axis it would be
60 1 10

10 is quite a high figure of merit - the default is 5.
