Do you mean that you want to solve an equation repeatedly using sets of
parameter values read from a file? One way would be something like this:
p = ReadList[ "file", {Number, Number, ... Number} ];
(* reads parameters into p; see section 2.10.6 of the gospel according
to Wolfram for syntax *)
While[ !MemberQ[ p, EndOfFile ],
(* if the data file ended, p will contain the symbol EndOfFile in one
or more entries - if it ran out in the right place, p will be *all*
EndOfFiles - see p. 498)
<your code goes here>;
<output your solution someplace>;
p = ReadList[ "file", {Number, Number, ... Number} ]
(* grab the next round of parameters *)
];
(* when you get here, you're done *)
