functions and arrays

i need this:
---------------
; Function to call
Function test( arr_test$[100] )
For n = 0 To 99
Print arr_test$[n]
Next
End Function

; Main
Type kk
Field arr$[100]
End Type
k.kk = New kk
test( k\arr$ )
WaitKey
---------------
but the blitz3d compiler show me error, can you help me?

thx

iirc you can't do that with arrays ... (tho I could be wrong :) I never use arrays this way anyway)

Try banks! If your strings all have a fixed length, a bank is easy to use.

Please explain the bank idea. I've never used them.

*making a user-friendly banktext system example now*

You cannot pass an array to a function, but you can pass a type handle:

; Function to call
Function test( a.kk )
For n = 0 To 99
Print a\arr$[n]
Next
End Function

; Main
Type kk
Field arr$[99]
End Type
k.kk = New kk

;To get a visible result
For n=0 To 99
	k\arr[n]="Field "+n
Next

test( k )
WaitKey

here ya go..

I used 'notify' here.. 'print' caused some crashes here.. I guess you know what to do if you don't have B+ .. it's all fairly obvious.

bnk=CreateTextBank(10,40) ; 10:elements, 40:stringwidth

For t=0 To 9
	SetTextbankText(bnk,t,"BlitzMax - we're waiting "+t+" months")
Next


; lousy test function
test(bnk)

FreeBank bnk ; <-- rather don't forget this! always clean-up your mess :)

End

Function test(blah)

	For t=0 To TextbankElements(blah)-1
		Notify TextbankText(blah,t)
	Next
	
	Notify TextbankElements(blah)
	Notify TextbankWidth(blah)
	
End Function

YOU CAN PASS AN ARRAY TO A FUNCTION

All you have to do is remove the dollar sign from the print statement and it works
Why? god knows

the array is passed by refrence, so you can also shange the contents
the arrays have to be the same size

this works

; Function to call 
Function test( arr_test$[100] ) 
For n = 0 To 99 
Print arr_test[n] 
Next 
End Function 

; Main 
Type kk 
Field arr$[100] 
End Type 
k.kk = New kk 
k\arr[89]="hello"
k\arr[95]="wazzaa"
k\arr[99]="goodbye"
test( k\arr ) 
WaitKey 

Hmmm, wouldn't have guessed, now I just need to find a use for it.
