File input/output is part of Short Circuit's Console Program Basics selection.
Task

Create a file called   "output.txt",   and place in it the contents of the file   "input.txt",   via an intermediate variable.

In other words, your program will demonstrate:

   how to read from a file into a variable
   how to write a variable's contents into a file


Oneliners that skip the intermediate variable are of secondary interest — operating systems have copy commands for that.




include c:\cxpl\codes;
int  I, C;
char IntermediateVariable;
[IntermediateVariable:= GetHp;
I:= 0;
repeat  C:= ChIn(1);
        IntermediateVariable(I):= C;
        I:= I+1;
until C = $1A; \EOF
I:= 0;
repeat  C:= IntermediateVariable(I);
        I:= I+1;
        ChOut(0, C);
until C = $1A; \EOF
