<td><apll>L</apll> is a numeric vector of line numbers in the named function where the result of each statement on the line is traced when the corresponding line number is encountered. If <apll>L</apll> is an empty vector, the TRACE property of the named function is removed from all line numbers. If a number in <apll>L</apll> does not correspond to a line number in the named function, that number is ignored.</td>

<tr>
<td><apll>Z</apll> is a numeric vector subset of <apll>L</apll> where the named function traces the result of each statement on the corresponding line when encountered. The values in the result are in ascending order. A value of <apll>0</apll> in the result means that the result of the named function is traced just prior to leaving the function. The Display property of the result is OFF, meaning that the result does not display unless explicitly forced such as with <apll>⎕←</apll>.</td>
