I am currently a new pascal student and would like some quick help with
this problem involving procedures.

In the program there are two procedures:  The first reads in the users
input data and saves it in a variable.  The second procedure must use the
value stored to the variable in the first procedure to perform the given
operation.  What I need to know is how to use the value stored in the
variable in the first procedure in the second procedure.

YOUR HELP IS MUCH APPRETIATED!!

Declare the variable in the main program ,like this:

program xxx;
uses <unit names>;
var <variable>:<type>; {this is it}

procedure <name>;
begin
{store data to <variable> }
end;

procedure <name 2>;
begin
{output data from <variable>}
end;

begin

end.

PROCEDURE SecondOne(saved_data: integer);
{ This procedure does something with the 'saved_data' integer variable }

VAR int_data: integer;
BEGIN
        Writeln('The initial value of int_data is ', int_data);
        FirstOne(int_data);
        Writeln('After FirstOne(), the value of int_data is ', int_data);
        SecondOne(int_data);
        Writeln('After SecondOne(), the value of int_data is ', int_data)
END.

Hi Eric,

Let's walk through your questions:

PROCEDURE READ_USER_INPUT(VAR VALUE : DATATYPE {e.g. Byte, Word, etc});
BEGIN
  --> read the user input of type datatype
END;

VAR VALUE : DataType;  { This is a local variable, only used in this procedure }

BEGIN
  READ_USER_INPUT(VALUE);
  { Here you call the first procedure and use the variable VALUE }
  ---> do something with the user input data stored in VALUE.
END;

Hope this help.

    ARE YOU REALLY *NEW* IN PASCAL PROGRAMMING ????

    There are variables known as Global.

    This is your so simple solution.

    In the future, read manuals before posting.
