pard s0 li2116 fi0 ri1007 ql tx2494 tx2872 tx3250 fs16
fs28 Uses b objectAtIndex:b0 to find the right target and if it responds to the message b boolValueb0 it returns the related value. If the object does not respond to that message the value NO is returned (is NO really the best value for a failure ??)

pard s0 li2116 fi0 ri1007 ql tx2494 tx2872 tx3250 fs16
fs28 Uses b objectAtIndex:b0 to find the right target and if it responds to the message b charValueb0 it returns the related value. If the object does not respond to that message the value 0 is returned (is "0" really the best value for a failure ??)

pard s0 li2116 fi0 ri1007 ql tx2494 tx2872 tx3250 fs16
fs28 Uses b objectAtIndex:b0 to find the right target and if it responds to the message b doubleValueb0 it returns the related value. If the object does not respond to that message the value 0 is returned (is "0" really the best value for a failure ??)

fs28 If there are object in this array this methods returns the b objectAtIndexb0 0. Returns b nilb0 if the array is empty.
