Sub and Value Return

[merli]

Maybe stupid question but I did not find out way how to return more then one parameter from Sub. I would like to do something like this:

Sub MinMax (array(), array_max_index, min_index, max_index, min_value,
max_value)

min_value=array(0)
max_value=array(0)
min_index=0
max_index=0
For i=0 To array_max_index
If array(i)<min_value Then
min_value=array(i)
min_index=i
Else If array(i)>max_value Then
max_value=array(i)
max_index=i
End If
Next
End Sub

When I run this kind of code values for min,max values and indexes are not returned. In C language the values I want to return should be called by addresses with & symbol. Is there any way how to do it in Basic4PPC?

thnx

Use Global variables.
I believe returns from subs are limited.

Unfortunately you can't do what you want to do in B4PPC yet.
You cannot pass variables by reference to a sub routine and back.
You can only return a value, or you could have a look here: http://www.basic4ppc.com/forum/basic...ub-return.html

Hopefully it would come in the next version.

Best regards.

I know I can use Global variables, but using Global variables is "Way to Hell", because your Subroutines are limited in reusability at least naming of variables should be the same then. I hope guys behind this product will work on this. How do you cope with this? Using Global Vars or using Arrays or Stack?

I use global variables and global arrays.

Best regards.
