.TT20 { JSR P%+3 \ This line calls the line below as a subroutine, which \ does two twists before returning here, and then we \ fall through to the line below for another two \ twists, so the net effect of these two consecutive \ JSR calls is four twists, not counting the ones \ inside your head as you try to follow this process JSR P%+3 \ This line calls TT54 as a subroutine to do a twist, \ and then falls through into TT54 to do another twist \ before returning from the subroutine }
