# Special Effects

**In English:** A short SuperBASIC demonstration of the QL's RECOL command: in MODE 8 it opens a window with a message, then repeatedly cycles the window's border and recolours all the window's colours to one colour, stepping up and back down through the palette; a sound-effect BEEP line is left commented out. No explanatory text accompanies the listing.

*Printed title: EFFETS SPECIAUX. The article below is in French, as printed in QL_DOC n2 (February-March 1988).*
