I think it would be easiest to use an array of chars. Say this for example (if it works)

 Help with Code Tags 
 Pascal and Delphi Syntax (Toggle Plain Text) 
 
Var
     myEquation      : array[1..256] of char;
     Equ                 : string[255];
     my_file            :text;
 
BEGIN
 
assign(my_file, 'input.txt');
reset(my_file);
read(my_file, Equ);
myEquation := Equ
 
Writeln(myEquation[1..10])
Var
     myEquation      : array[1..256] of char;
     Equ                 : string[255];
     my_file            :text;

BEGIN

assign(my_file, 'input.txt');
reset(my_file);
read(my_file, Equ);
myEquation := Equ

Writeln(myEquation[1..10])

not sure if this helps at all, but that would atleast put my equation into the array and display the equation (had the writeln to make sure the equation was in the array)

Hey man, I totally appreciate all the help you've given me during this massive thread (and I have learnt stuff). But this assignment is due tomorrow, so I am just going to throw together what I have and hope for the best.

THe next assignment I have is the same concept but I am suppose to use linked lists as the main storage of the equation (records and arrays are allowed)

Ah well, sorry I didn't see this sooner. If it is due today then there's not much more to do here.

If all you wanted to do was store your equation as a string (an array of characters), then we've gone in loops for the wrong assignment.

All the stuff you've done helps, and will help you in your next assignment especially...
