Simple Text-Based Page-Display System

[DarknessX]

Just a simple page display system which will list the entire contents of an array until it meets an empty number (ie, timer[76] = 't' and timer[77] = ''). It shows it in page format, with a configurable number of items per page, by customizing the 'listnuma' value. Non-Commented version at the bottom.

Note: This code is being used in my upcoming Task Scheduler I am creating.

Timer 1: g

Timer 2: g

Timer 3: g

Procedure ListItems;
begin
x := 1; {Set X as one. This should be whatever you want the first item to be.}
Repeat {Create the first lpage}
if timer[x] <> '' then begin {timer[1..50] is what I have set.}
Writeln('Timer ',x,': ',timer[x]); {Writes to screen the current number of X, in my case, the current list item, then the name of the timer.. the name of the timer would be timer[1].}
bool := false; {bool is false, to say that the current list item is NOT empty. If empty, it closes the loop and thats the last item shown.}
x := x+1; {Increment the current list item by one.}
Readln; {Pause. Not necessary, remove as wished.}
end else begin writeln('EMPTY!'); bool := true; readln; end; {If timer[x] = '' (empty) then say 'empty'. ONLY the bool := true statement in this end... else is necessary.}
Until (x = listnuma+1) or (bool = true); {listnuma is the user-configurable number that you want displayed per page. if listnuma is set to 5, 5 items are displayed per page. If bool not equal to true, then continue with next page.}
ClrScr; {Clear the screen... open a new page.}
if bool = false then begin {Bool must be false, meaning, the current item cannot be empty, for next page to continue.}
listnumx := listnuma; {This here is outside the second page loop. This sets listnumx (the first value of the next page) to the max value of the last.}
listnumz := listnuma+listnuma; {This sets the maximum value (last item on the page)}
Repeat {Begin the actual loop for EVERY SINGLE following page, not just one.}
Repeat {show the page loop}
if timer[x] = '' then bool := true; {Is the timer empty?}
if timer[x] <> '' then begin {If the timer is not empty, then...}
Writeln('Timer ',x,': ',timer[x]); {Show the list item... Same as above.}
x := x+1; {Increment x by 1.}
bool := false; {Bool stays false, since the item is not empty.}
Readln; {not necessary, just for a pause. Depends how quick you want the items shown on screen.}
end;
Until (x = listnumz) or (bool = true); {Is the current item either empty, or the last item?}
listnumz := listnumz+listnuma; {Create the new last page. Will do nothing if the current item is empty...}
ClrScr; {Show new page}
Until bool = true; {All pages shown.}
end;
end;

So was this of any use to anybody?
