 +====== IOP.SWDF ====== 
 +This trap sets a pointer to the application sub-window list in the window channel block. 
 +^Call Parameters^^Return Parameters^^ 
 +|D0.B|$7D|D0.L|Error return| 
 +|D3.W|Timeout|D3.L|Preserved| 
 +|A0.L|Window channel ID|A0.L|Preserved| 
 +|A1.L|Pointer to the list|A1.L|Preserved| 
 +==== Error ==== 
 +|ERR_NO|Channel not open| 
 +==== Notes ==== 
 +  * All registers not mentioned above are unused and preserved. 
 +  * This very simple trap just places the address in A1 in sd_sewll of the channel block. The trap seems to be rarely if ever used by the PE software and seems of no practical use to a programmer.
