<h1><apl>{quad}LC</apl> - Line Counter</h1>

<apll>{quad}LC</apll> is an ISO 13751 standard niladic system function which returns an array of the current line numbers of
every current function. Consider the following workspace:
<apll>{del} test [1] 'LC=' {quad}LC {del} {del} test2 [1] 'Calling Test' [2] test {del} </apll>
So the following commands would produce the following output:
<apll>     test LC= 1      test2 Calling Test LC= 1 2</apll>

<apll>{quad}LC</apll> is a ''niladic'' function, you cannot assign a value to it.
