Hello, well i've been trying to make a program a program that will read from a text file the first num. of the firs line, and then will do a certain procedure, that means a procedura that will read the other nums. into arrays, as many times as the value of the first num is. This is the program i've made, but the compiler has errors. Is that possibly because i have not put in every procedure a for i:=1 to n do or for i:=1 to 100000 do?
Can anyone please help me?

Program filetext;
Var
a:array[1..100000] of integer;
b:array[1..100000] of integer;
c,d,i,j:Integer;
f:Text;
Procedure thenum ;
Begin
repeat
Read (f,a[i]);
Write(a[i]);
until (a[i]=' ');
End;

Procedure sth ;
begin
while not seekEoln and eof(f) do
begin
read(f,j[i]);
Write(j[i]);
end;
End;
Procedure theprogram;
thenum;
space;
sth;

procedure space;
begin
Reset(f);
Read(f,c);
Write(c);
end;

begin
Assign(f,'textfile.txt');
Reset(f);
repeat
Read (f,n);
Write(n);
until (n=' ');
End;

Read(f,c);
Write(c);
while not seekEoln and eof(f) do
begin
read(f,d);
Write(d);
end;
for i:=1  to n do
theprogram;
Close(f);
Readln;
End.

You should report the exact error messages, on order to get help.
I tried to compile it with Free Pascal Compiler, getting:

filetext.pas(12,13) Error: Incompatible types: got "Char" expected "Int64"
filetext.pas(19,10) Error: Illegal qualifier
filetext.pas(20,9) Error: Illegal qualifier
filetext.pas(24,1) Fatal: Syntax error, "BEGIN" expected but "identifier THENUM" found

First error reports a type mismatch: you cannot compare integers to characters:

Quote:
until (a[i]=' ');

You could fix it, for instance this way (if it makes sense to you)

until (a[i]=-1);

Second (and third) error occurs because you are using an integer like an array.

Quote:
read(f,j[i]);
Write(j[i]);

You cannot subscript a integer variable (an array is required).

Fourth error: BEGIN is required: you forgot to put BEGIN immediately below the

Quote:
Procedure theprogram;

line.
