Hi,
I am looking for a some help in reading the file from teh sturct.
Fo example, I have sturct files named 'A' , 'B' , 'C' ,'D' etc. and inside each struct file I have many arrays stored (e.g. X, Y, Z,) inside teh struct file A.
Now, to call array 'X' from the each struct file I am using A.X; B.X; C.X; D.X. Though this is working fine and in my code everytime I have to change X and Y manually wherever thats been called. Is there any aletrnative way, essentially I am looking for something like
S = X;
A.S
B.S
C.S
D.S

It's in the form of 1x1 struct

"I have sturct files named 'A' , 'B' , 'C' ,'D' etc."
A file is some data saved on a storage device (e.g. hard-drive): https://en.wikipedia.org/wiki/Computer_file
A structure is a data class used in MATLAB memory: https://www.mathworks.com/help/matlab/structures.html
What is a "struct file" ? I have never heard of such a thing, nor is it clear how such a thing would even exist, or be used.

S = 'X';
A.(S)
B.(S)
C.(S)
D.(S)
This is called "dynamic field names".

"e.g if I have number 60 stored in some variable C, is it possible to use like this"
It is certainly possible, if you want to force yourself into writing slow, complex, inefficient, obfuscated, insecure, buggy code that is hard to debug:
Best avoided.
Use indexing, just like MATLAB is designed for.

@Turbulence Analysis: Stephen23 hits the point. Read and consider the linked tutorial carefully.
T3 = A_60.X2 looks like you have hidden the indices 3, 60 and 2 in the names of the variables or fields. This makes it much harder to access the fields, while using real indices is trivial:
T(3) = A(60).X(2)
