: Hi, I really need some help with Pascal. I took a five month high school course on think Pascal, we did types, arrays, functions,procedures,polys etc, but we never got into any of the complicated stuff like pointers and resources. Now I have written out a program that's just a little bit too long. I need to brake my program up into a couple smaller parts right? How? I make a new one of those .p files, then add it to my program. I always get errors like, "there are two main programs", or "uses expected here". There are some special things I have to write such as: uses, interfaces, and implementation, but after a lot of net searching I can’t figure it out. I could use some help please.
:
You mean you want to know how to write units. Here is the basic appearance of a unit:
unit UnitName; { this name must be equal to the filename }
interface
{ here you declare all the functions/procedures/variables/types which
are to be used by the program. example:}
procedure WriteProgName; { Note: begin-end part }
implementation
uses
Crt;
{ here you declare all the private functions/procedures/variables/types.
You also write the implementations of the previously declared
routines. }
procedure WriteProgName;
begin
Clrscr;
writeln('My program');
writeln;
writeln('Designed by: me');
end;
end.
In your program you can add UnitName to the uses list and then use WriteProgName like any other procedure. I hope this was what you were looking for.
