[OS X TeX] using variables in text via references or labels

[Gert van Oss]

dear all,

I've had some problem making up a clear subject line and stil am in  
doubt whether I've succeded. What I'm trying to achieve is the  
following.

My documents have often various tables and charts embedded via the

    \input{table_file}

command.

While explaining my tables/charts I'm mentioning actual numbers (as  
listed in the tables) in my text. Is it somehow possible to create a  
list of numbers in my latex document and have them called via a  
reference in my text? This would enable me to run a somewhat related  
scenario in my numbers and udpate both my tables with numbers and have  
all numbers changed in the text as well.

I was thinking this should be possible while using \labels, \ref but  
for the moment can't stretch my mind to find a solution.

Thanks for any reply,

Gert
