Clearing hashes

[Mattwatters]

Could someone please let me know of anyway way of clearing hases. I have tried %whatever = null; but this this does funny things to my tables i am creating from them i.e. it always inserts a zero for some reason where thre shouldnt be one.

cheers

%whatever=();

or

%whatever=undef;

 

[icrf]

[tt]%hash = undef;[/tt] actually creates a single key, undef, with no value (essentially undef). It should spit back a warning about an odd number of arguments in a hash assignment. You can say [tt]undef %hash;[/tt] and it works as well as your [tt]%hash = ();[/tt]

...but I'm just a C man trying to see the light

delete %hash;

will also work well.

 

[daverston]

undef %hash;

also works too.
