```Hi,

Question (partially Mathematica, partially Linux):

We have to pass two values  (one integer and one string)
to a  mathematica foo.m running in batch.
The integer is simply used in a sum;
the string has to be concatenated into a file name (Output)
^^^^^^^^^^^^

Let's imagine to have the following trivial program  "foo.m"
which requires two inputs (one integer and one string)
from the keyboard
BUT has to run in **batch** (Linux with Mathematica 4.1).

*** foo.m begins ****
Clear["Global`*"]
a = 1;
number = Input["Enter number, e.g.,  99 : "];
sumnumber = a + number;
sumnumber >> foo1.out
string = Input["Enter the string, e.g.,  1212_800 : "]
string >>> foo1.out
m1 = MemoryInUse[]
sol = NDSolve[{y''[x] - y'[x] + y[x] ==0,y[0]==1,y'[0]=1},y[x],{x,0,3}]
m2 = MemoryInUse[]
m3 = (m2-m1) >>> foo???????.out

(*We have to replace foo???????.out with foo1212_800.out
where 1212_800 is read from the following batchfoo.com *)

**** foo.m end ***********

The relevant batchfoo.com (executable)
contains

math <<end1  >>foo.out
<<foo.m
99
"1212_800"
end1

The trouble lies in the line
m3 = (m2-m1) >>> foo??????.out

What shall we have to do in order to get
foo1212_800.out ?

Can you tell us how to modify the foo.m and the script ?
Several trials with, e.g., ToString failed.
