Custom property set

[Sarah Reichelt]

Hi All,

Having a total brain freeze here and can't work out how to get the
keys of an array which is a custom property set.

I have a custom property array: cStoredData[whatever] with about 12
blocks of data stored in this array e.g. cStoredData["Temperature"],
cStoredData["pH"] etc.
How do I get a list of the keys i.e. Temperature, pH etc.?

I've tried:
    put the keys of the cStoredData of this stack
but that won't compile.

TIA,
Sarah
