- function More: string;
- var
- Prompt: char;
- begin
- More:='';
- if Pause and (Lines=mem[$40:$84]) then
- begin
- write('Continue - [Y]es, [N]o? ');
- Prompt:=ReadKey;
- writeln(upcase(Prompt));
- if Prompt in ['N','n'] then
- halt(0)
- Lines:=0
- end;
- inc(Lines)
- end; {More}

- Pause and Lines are both global variables. Since I call the function
- from many other functions/procedures I decided it would be less work
- then passing them through. Pause is simple a flag deciding whether or
- not you want pausing or not. You may not want to take the same action I
- did when the user doesn't want to continue. The mem command looks at
- memory location 0040:0084 which contains the number of lines on the
- screen. This prevents the need to check what mode the screen is in.
-
- Anyways, the way I used it is as follows:
-
- writeln(More,'What ever you may want to display');
-
- Since functions are executed first, it determines wheter or not to
- display the line or prompt to continue.
-
- Hope that helps... (assuming you can figure out my explanations)
