Do may refer to any of the following:

  1. A “do” is a loop statement in programming that performs pre-defined tasks while or until a pre-determined condition is met. For example, in the below Perl code the do loop runs until the $count variable has reached the value of 9.

my $count = 0; do { print “$count\n”; $count++; } until ($count >= 10);

  1. The Internet domain suffix .do is short for Dominican Republic.

Like any loop, when creating a do loop make sure it contains an exit condition (e.g., counter) that prevents an endless loop.
