[TxMt] using numbers 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 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
