That's amazing!! And to think I tried to make a simulated DLL in LB.. Essentially, what you showed me would allow me to make modules for many things.
I would also suppose you would surprise me further and say that LBB could also be used to somehow make a DLL?

Actually it can't, or at least I've never worked out a way to do it (I'm not sure whether it's theoretically possible or not).

I tried to make include work in LBB but the program doesn't recognize it. I put it at the end of my main program and then executed it.
Because of the missing program module (subroutines that are separated from the program and saved in a separate .bas file)
I looked at the links concerning it in LBB and I cant figure why it doesn't work.
And a little subject for your amusement:

Most likely reasons:
Not starting in the first column. Unlike a conventional comment, 'include must be at the very beginning of the line.
No CRLF afterwards. If you are putting it at the very end of the program, make sure you have added a newline after the filename. Richard.

Obviously I am doing something wrong.
lets say this is my main program.. I have include at the start of the program: (the program wont run if the sub is put there.)
Code:
'include mytools.bas
nomainwin
open "The sphere subroutine !!Created by Michael Gallup (free for the public to use)" for graphics_nsb_fs as #1
#1 "trapclose [quit]"
#1 "fill black ; home ; down ; north"
'************H***V***S***R***G***B**Dimmer
call sphere 500,500,220,225,240,250,1
call sphere 50,50,25,225,240,250,9
call sphere 100,100,50,200,200,200,4
call sphere 200,200,100,140,200,200,2
wait
[quit]
close #1
end
and here is the program it would add to the above code.
I would have saved it as mytools.bas
do you know how it would be corrected?
Also the code bellow would need to be put at the base of the program.
Code:
sub sphere h,v,size,x,c,a,dimmer ' dimmer cannot be more than 24
#1 "place ";h;" ";v
for y=1 to size
#1 "down"
#1 "color ";x;" ";c;" ";a
#1 "size 2"
#1 "circle ";y
#1 "flush"
x=x-dimmer
c=c-dimmer
a=a-dimmer
if x<2 then x=2
if c<2 then c=2
if a<2 then a=2
next y
end sub

'include
doesn't work as a first line.
It is documented in a help file:
Quote:| For maximum compatibility with Liberty BASIC Workshop the 'include directive is ignored when it is at the very beginning of the program. See this Wiki article for more information, and for details of how to integrate LBW with LBB. |

The use of flush in the middle of the loop is not appropriate. If you ran this in LB with a size of 200 then every time the window was moved minimised or restored there would be 200 drawing actions. Perhaps not with LBB but certainly with LB.
Flush should be use sparingly and at the end of a looped or multiplexed drawing routine.

The effect won't be so serious in LBB, but it will certainly slow the program down so it's not a good idea. If you're writing a program to run only in LBB, I would recommend not using FLUSH (although it can still be useful when paired with REDRAW). If you want the code to run in both LB and LBB then use FLUSH but ensure it doesn't result in a memory leak (e.g. using CLS or DELSEGMENT to free the memory).
Richard.

That's fine. It doesn't take me long to copy/paste my main program onto a template.
I will just make a Program generator to merge the files together quickly into a new program.
Because that's what I do best.
I am using LBB just for the fact that it makes stand alone executables and for the fact it allows continuous draws.
I could use the other resources like gxGL and OpenGL and some other method Richard used in old forum posts for 3D magic, but that's a bit over me since I have only been serious on LB since last January 2015..

Can I just reiterate that 'include works correctly in LBB, as documented. If it serves your purpose (and it's ideal for the gxGraphics library) then use it.
Richard.
