I think You are trying to find a solution to the not best way of using 
Mathematica. Better to change the method you are using.

I would put each command in a separate cell. This way, you will have one 
command followed by its output below it. I like to also use the Report 
style sheet, this makes output cells more clear.

But if you want to have more than one command in the same cell, you 
could always use Print[] to print the output of the command, and this 
way you can add a string label to the Print command to help you 
determine which command it was.

Something like

Print["x=", x = Pi/2];
Print["a=", a = Sin[x]];
Print["c=", c = Sin[x]];

x=Pi/2
a=1
c=1

OR

x = Pi/2;
Print["x=",%];

a = Sin[x]];
Print["a=", %];

etc...
