[Coco] Error in BASIC manual. ?

[coco at jechar.ca]

I tried putting

30  HLINE (22,33 )-(100,90) ,3,BF

in a basic program but when I run it I get
?SN ERROR IN 30

I followed the manual example exactly and I have
included the entry for this command from a PDF of the
manual in the coco archives as you can see I copied
the command exactly so why am I getting an error ?
