variable's scope of for...next loop

variable's scope of for...next loop

I write some code like:

first:

For $i =1  To 2  Step 1 
 For $i =6  To 7  Step 1 
  MsgBox(0,"in",$i) 
 Next 
 MsgBox(0,"out",$i) 
Next oÝ÷ ÚØ^­ë.جÖ)

the result is:

1 in=6

2 in=7

3 out=1

4 in=6

5 in=7

6 out=2

It' done!

but most program language can write code like the first.

Okay, what's your point? AutoIt obviously can't. Scope is at the function level or the global level. Loops do not have their own scope.

For $i =1  To 2  Step 1 
 For $i =6  To 7  Step 1 
  MsgBox(0,"in",$i) 
 Next 
 MsgBox(0,"out",$i) 
Next

This is not good programming practice in any language, regardless of scope issues. Your code makes it impossible to reference the outer loop variable from the inner loop, which is a common need in most nested loop structures.

Thanks! I see!

AutoIt is a great, and powerful scripting language!
