defined string as input for function

I have function which use load file that have some string inside it which I used it as input to my function so, I defined the load file and the input as the following:

load(file1) //file1 name is defined up so, I can change it any time

and I defined the input like

x11= low;
y11= vlow;

then in the function I defined the input as

x=x11;
y=y11;

but when I run it t give me undefined variables low & vlow. In addition, if I write x=low & y=vlow with out define it up it work .

load() does not execute MATLAB commands present in text files. If you want to execute MATLAB commands in a file then you should run() the file.

by the way this function I use it in GUI, it still not clear to my how I can solve this problem

[Walter Roberson]

When x11 is mentioned, then is it expected to have the same content as a previously-defined variable named low, or is it expected to contain the string 'low' ? If it is expected to have a copy of the previously-defined variable named low then which workspace has that variable been defined in?

[Ahmed Alshehhi]

it is defined in the load file

[Walter Roberson]

Is the file being loaded a .mat file, is is a text file containing the lines

x11= low;
y11= vlow;

and before that in the text file there is an assignment to the variables 'low' and 'vlow' ??
