I am simply calling this:

Global dim myValues as integer = [5,9,4,8,3,7,2,6,1,10]

But print(str(myValues[5])) = 0????

Ive also tried:

Global dim myValues = [5,9,4,8,3,7,2,6,1,10]

But then it wont compile... even though im following this...

Thanks
Andy

For instance, this doesnt work:

+ Code Snippet

rem
rem AGK Application
rem
rem example 2
dim myValues [ 3 ] as integer = [12, 492, 450]

rem A Wizard Did It!
do
 print ( myValues [ 0 ] )
print ( myValues [ 1 ] )
print ( myValues [ 2 ] )
 Sync()
loop

all 3 prints are 0

Thanks

I'm no expert on the Basic, but shouldn't it be:

Global dim myValues[10] as integer = [5,9,4,8,3,7,2,6,1,10]

This is a static array, so the compiler needs to know how long it is!

EDIT: I seem to remember reading that a dim of [10] in AppGameKit actually allocates 11 (0..10), but I may be wrong. Often am.

It's a bit clearer in Pascal:

var myValues : array [0..9] of integer;

-- Jim DO IT FASTER, EASIER AND BETTER WITH AppGameKit FOR PASCAL

You need to enter the number of items in array then it will work.

global dim myValues[10] as integer = [5,9,4,8,3,7,2,6,1,10]

EDIT:
print(str(myValues[5])) actually prints number 7 because arrays start at item number 0

Sorry was a typo in the forum not code.

my code does display the size.

Global dim myValues[10] as integer = [5,9,4,8,3,7,2,6,1,10]

Still doesnt work.

Thanks

I just copied your code from above and pasted it into a new project - it worked fine for me:

+ Code Snippet

rem
rem AGK Application
rem
rem example 2
dim myValues [ 3 ] as integer = [12, 492, 450]

rem A Wizard Did It!
do
 print ( myValues [ 0 ] )
print ( myValues [ 1 ] )
print ( myValues [ 2 ] )
 Sync()
loop

If you put the above code into a new project does it work?
