I agree that it was not what was expected but it does fulfill the criteria as stated. The answer was probably supposed to be this as noted elsewhere:
$[ The index of the first element in an array, and of the first character + in a substring. Default is 0, but you could theoretically set it to +1 to make Perl behave more like awk (or Fortran) when subscripting an +d when evaluating the index() and substr() functions. (Mnemonic: [ be +gins subscripts.) As of release 5 of Perl, assignment to $[ is treated as a compiler dir +ective, and cannot influence the behavior of any other file. --> Its +use is highly discouraged :-) $[ = 1; $x[0] = 1; show(); $x[0] = 2; show(); $x[1] = 3; show(); sub show { print "\$x[$_] = $x[$_]\n" for 0..$#x; }
