Re: loading a file using a variable name

[oxyopes]

Hi,
filename = 'exp/fpdata.dat';
load(filename)   works, but only of filename is a data file,
not if it sets a couple of variables. In the latter case,
i cannot execute it if i can only refere to the name through
a variable, like just writing filename at the prompt.
Is there a way to do that?
