Hi Arno there's a bug when loading old scasm source. It has been "inserted" into v. 0.13 - I've verified that v. 0.12 works fine with the following instruction (from scasm doc): Code: RotatedCall( :Label pitch bank heading ) The subroutine at :Label is called with rotated coordinates. The pivot point is the active RefPoint(). pitch Pitch angle. Positive values are nose down. bank Bank angle heading Heading angle "Heading" attribute is now swapped with "Bank" attr. cheers || Edit 12:00 GMT || It looks like ther's a faulty common routine. Same bug with Scasm "TransformCall".
