I'm not sure if this is well known or not it is possible to have a static variable in a function.

To do so use a Global.

i.e.

strict 
Function MyTest(flag : int = 0)
   
   global static : int
  
   if flag = 0
      static:+1
   else
      print static
   end if

end function

for local i : int = 0 to 4
    MyTest()
next

MyTest(1)
End

Running the above example will print 5 instead of 1 as it would if a local variable were to be used in stead.

Cheers.

As far as I'm concerned, this is already common knowledge.

On another note, you can have nested functions too.

function foo()
bar()
function bar()
print "called from foo"
end function
end function

not seen in the docs or should i say it..... the wiki?

plus recently some one posted a request for statics in the update forum and was advised to use a type with a global!

did not know that functions could be nested. could lead to some pretty nasty code :D

cheers.

thats why it isn't in the docs I think ;-)
wouldn't lead to a nice coding style but even worse stuff than C++ programmer already do ;)
