How can I declare a string variable which I can call when loading a filename?

I want to plot files amongst which the only thing that changes is a word. Therefore, I want to declare a variable which I can call in the filename. Model=(CanESM); load('Model.mean.dat'); ...

model='Model.mean.dat'
load(model);

I understand what you want to say, but I want to declare the string 'Model' as a variable and not the whole file. I want to write "Model" in the filename and read the file CanESM.mean.dat.

Model = 'CanESM';
load( [Model '.mean.dat'] )

[Azzi Abdelmalek]

Model='CanESM';
file=sprintf('%s.mean.dat',Model)
load(file)
