It is assumed that A0 contains the window's ID. <code> brdr moveq #sd_brdr,d0 ; $0C moveq #-1,d1 ; Grey border moveq #3,d2 ; Width 3 moveq #-1,d3 ; Timeout trap #3 ; Set the border tst.l d0 ; OK? . . bne error ; . . no! </code> qdosmsq/traps/trap_3/defb.txt Last modified: 2009/05/17 14:47by george.gwilt
