Sample to create cerificates not working

Howdy,

I am trying to create a certificate on ROS (6.23) , using this sample from the wiki

http://wiki.mikrotik.com/wiki/Manual:Create_Certificates

however

sign template=ca-template ca-crl-host=10.5.101.16 name=myCa

gives me an error: expected end of command ( line1 column 15 )

it that a syntax error in the sample ? What would be the correct line?

Thanks
Oskar
