Hi,

I've been working on a program and each time i run it, it comes up wiht an error runtime 102. I know it might have something to do with Assign, Amend etc functions but can't figure out exactly where i went wrong. Here's an example script.

Begin
  Assign(oldd,'DDNAMEold.txt');
  reset(oldd);
  REPEAT read (oldd,ystart,yddstart,P);
  UNTIL eof(oldd);
End

I've got this program from another person who's been working on this before me. I'm a complete beginner and has been spending a week learning how to use Pascal. Would appreciate it if someone can point out where I've gone wrong and also how to fix it!

Thank you!

Janie

Try this:

  While not eof(oldd) do
    readln(oldd,ystart,yddstart,P);

Otherwise the program will not jump to the next line.

Also, you should check the variables: you can't read separate strings like this, only numbers.

Hi,

if you have something like:

procedure mygoodprocedure
var
oldd : text
begin

then I would sugest that you put "text" line above:

unit myunit
...
var
oldd : text
...

procedure mygoodprocedure
var
...
begin

The file should be "global" , not in a procedure

goog luck
