# 4D_WriteObj(ObjType, ObjIndex, Value) hash function
Sends the number Value to the nominated 4D object. Value is converted to the 16-bit integer data expected by ViSi-Genie, so possible values lie between 0 and 65,535.
ObjType is the 4D systems Object. These are defined in the ViSi-Genie reference manual. ObjIndex is the object number of that particular type.
Executing this hash function will always result in one YieldTask.
Example:
k4D_Led EQU 14 ;4D's LED object type ... # 4D_ViSi 4D_WriteObj(k4D_Led, 6, 1) ;Turn on LED number 6 # 4D_ViSi 4D_WriteObj(k4D_Led, 3, 0) ;Turn off LED number 3
