Have you checked that its got enough oil in?

Could it be the clutch release bearing

100A's do have whiney gearboxes, especially when resting your foot on the clutch pedal without actually pressing it in. They're also noisy in 1st gear.

Get yourself a Haynes Manual it will be useful

Without checking the Haynes manual I cant give you a detailed instruction. There is most likely a plug on the side of the gearbox, which will need screwing out. You can then get a squeezy bottle of gear oil and stick the end of the bottle tube into the hole where you removed the plug. Squeeze and fill until oil begins to trickle out of the hole, meaning the oil is up to the level of the bottom of the hole. Wipe off excess oil and refit plug.

Do it with the car level, not sloping.

Not sure how much you got from Wills writings already but an E10-F10-N10 gearbox always whines as just like a Mini the box is below the engine and 3 cogs transfer the power from the clutch to the gearbox. When you press the clutch the strain is taken off the gears so they become quiet, and when not driving they stop turning. So whining is part of the deal and charm of these Datsuns.
Checking the oil is good anyway and the plug for that is located on the front side of the car. If you look through the gap between the front valance and the subframe you will see a plug with a square hole, that will take a 1/2 socket extention to remove. That is the filler plug and also the level (top up until the level reaches the bottom of the hole, make sure the car is level when doing this!)
Have fun and good luck!

No, don't put it in there otherwise you will never be able to tell when the correct level has been reached. See Iwan's post about the location of the filler hole.
