Re^3: loop problem

What error does strict throw? Works fine for me as-is on 5.26.1.

Anyway, here's an example of how to get what you want:

my $radius = -1;

until ($radius >= 0){
    say "What is the radius?";
    $radius= <STDIN>;
    chomp ($radius);
    say "radius must be >= 0. Try again...";
}

Regarding your question: if I run the program with the submodule with strict, I get this output: Variable "$radius" is not imported at circum1.pl line 19. Variable "$radius" is not imported at circum1.pl line 20. Variable "$radius" is not imported at circum1.pl line 23. Variable "$c" is not imported at circum1.pl line 30. Global symbol "$radius" requires explicit package name (did you forget + to declare "my $radius"?) at circum1.pl line 19. Global symbol "$radius" requires explicit package name (did you forget + to declare "my $radius"?) at circum1.pl line 20. Global symbol "$radius" requires explicit package name (did you forget + to declare "my $radius"?) at circum1.pl line 23. Global symbol "$c" requires explicit package name (did you forget to d +eclare "my $c"?) at circum1.pl line 30. Execution of circum1.pl aborted due to compilation errors.

If you're getting those errors/warnings, then the code you posted isn't the code you're running I don't suspect. The only issue that I see with syntax is a missing semi-colon after `say "circumference= ", $c` If that doesn't fix things, please post the actual code you're using.	[reply] [d/l]

The code with the submodule in it gives these errormessages. I ran it again and again.	[reply]
