Hello List,
Hello,
I'm trying to grep an array of arrays, but I am getting the following error:
Can't use string ("1") as an ARRAY ref while "strict refs" in use at
form.pl line 121,<$COORDS> line 1281.
Press any key to continue . . .
Below is the grep statement:
print grep { $_->[0][0]>= 0 } @coords;
Any idea what I am doing wrong?
If @coords is just an Array of Arrays then that should be:
print grep { $_->[0] >= 0 } @coords;
Your example thinks @coords is an Array of Arrays of Arrays.
