Eloy,
You can set up an "array" -- a property that have several (indexed) values.
Assuming that you are reading data that is all the same type (floating
point in this case) and you keep track of the position of the values, and
you ignore the automatic temperature scale conversion this would work well.
When you read eloy.ALL you would get "27.3,90.2,1003"
A bigger question is why you want this? The cost of the "file commands" is
very low -- there is no actual file activity -- these are all virtual FUSE
files.
