Question: How to recover the content of .m files ?

hello everyone, 

To illustrate my question I will get Bob and Alice 

Suppose Bob and Alice work separately on the same subject and must share some information.
They decide to exchange information among themselves by using .m files (Maple internal format files).


1) Bob performs the first serie of calculus which ends by some "result". 
This result is the information Bob must send to Alice for her doing her part of the job.
Bob assigns this result to a variable named MyVar and saves it in a .m file :

MyVar := ... :
save  MyVar   "/.../MyFile.m"

Then Bob indicates to Alice the complete path to MyFile.m ... but forgets to say her the name of the variable he has saved.


2) Alice reads the file MyFile.m (read "/.../MyFile.m") .... 
Of course, if Alice knew the name of the variable Bob used in his "save" command, it would be the simplest thing in the World for her to browse the content of the .m file (eval(MyVar) generally works well).

But I assumed it is not the case, so my question :

Can Alice recover the name of the variable and visualize it ? 

Any answer will be greatly appreciated

postscript : it is not the first time I find myself in the situation Alice faces here. Often I have to recover the content of .m files written years ago by people who have changed their core business without having properly documented (like Bob) what these files contain

Please Wait...
