Re: loading a file using a variable name

[James Sherman Jr.]

I'm not exactly sure what you mean here.  The function "load" is used to read variables that have been stored in a file (using "save" or other means), not to execute code.

If you want to save two variables such as var1 and var2 to a file called "
var.dat",  then you could do something like:
> var1 = 100;
> var2 = 200;
> save("var.dat", "var1", "var2");
then to recover them,
> load("var.dat");

If on the other hand you wanted a script that declared var1 and var2 as above, you could put (like David said) the lines:
var1 = 100;
var2 = 200;
in a file called "var.m", then (assuming it is in your present directory or path) type
> var
at the command line.

Hope this helps.

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?
