yes, you unrapped a line break and as such, "not(...:not(..." is better than an "not(Ans:"...if I had a third line of conditionals in there, it would be better my way though

But there is a problem with both of ours, when you run it if xlib isn't installed then it says "Install Xlib!" but now the Ans is "Install Xlib!" so it receives a DATA TYPE error. So in order to stop that just place the first1 in a If Then
c1

-->

CODE

ec11
real(0
If not(Ans:Then
Pause "Install Xlib!
Return
Endc2

ec2
Then just place the rest of the code after End (The rest of the program).

Also, you misspelled Install.

that's nice to know, Tr1pl1ea should include that peice of code in the readme so all games with xlib uses it

Well if xlib gets turned into a basic xlib game app it will not need the code above.

I guess that is a vote for my proposal of making an xlib shell?

Oh well I have been for it just didn't want Pat getting tired of working on it.

Apparently expr( doesn't work with the Goto command either, that's a shame.

DJ Omnimaga · « **Reply #99 on:** January 12, 2006, 04:17:00 pm »

too bad

at least does it work with useful commands?

dysfunction · « **Reply #100 on:** January 12, 2006, 04:22:00 pm »

It does work with many useful commands.

On a slightly different topic, does anyone know a way in which I can jump to a section of program according to the number stored in a variable? Say variable A=5, is there a way to then Goto 5, or Goto 27 if A=27, etc?

kalan_vod · « **Reply #101 on:** January 12, 2006, 05:05:00 pm »

No but you could do

c1-->

CODE

ec1A
If Ans=1:Goto 1
If Ans=2:Goto 2
If Ans=3:Goto 3
....
etcc2

Depends on what you are doing, but you can use While statments like goto/lbl commands, by manipulating the variable values...

Just keep everything in one big loop, say like this:

While W>0
All your fancy While commands go here
End
Return

And if you want out of the loops, just delvar W...

Make sense?

Yeah and no memory leaks

my 2 cents...

int(log(#)+1 = How many digits the number is

example

Text(0,0,sub(" 00000000",1,8-int(log(S)+1)),S

will return an 8 digit number at 0,0 on the GS no matter what (if S's digits are less than
