AMOS:Bug spelling

'Track Loop Of' really is an instruction in AMOSPro. Ofcourse it should have been 'Track Loop Off' (with two f's).

• The AMOS Professional manual uses the correct spelling 'Track Loop Off', which won't work.
• The only place which uses the correct spelling, which won't work in AMOSPro is the demo for the instruction which, when run shows 'Track Loop Off'.
• The AMOS help and the notes in the demo-sourcecode call it 'Track Loop Of'
• The AMOS help links to 'TRACKLOOPOFF' as articlename
  (although you won't see this because the AMOShelp looks for the article with the most matching chars on the left)
