it allows you to choose the increment of the variable in the For...Next loop

EX:

For $i = 5 to 0 step -1
Msgbox(0,"",$i)
Next

This code will count from 5 down to 0. If we hadn't had the "step -1" in there, it would be trying to count up by 1(default) to get to zero which would obviously never happen.

Are you asking for an example?

For $i = 1 to 100 Step 10

Consolewrite(@crlf & $i)

Next

Consolewrite(@crlf & "---------------")

For $i = 100 to 1 Step -10

Consolewrite(@crlf & $i)

Next

if i write

for $n = 5 to 0

MSgbox(0,"",$n)

Next [code=auto:0]

what's happen , i can see the number from 0 to 5

Why ?

Because unless a "step" is defined, it starts at the first number (in this case, 5) and counts up until it gets to the second number (in this case, 0) obviously, you can't count up to zero from 5, so the script fails. Edited July 19, 2008 by Paulie

why do u use -1 at step but why dont u use 2 or 3 or ........

help me that question please

that is last question if i understand , please

Step moves forward or backward the number you provide for it.

Step with a positive number after: Step 1 or Step 2 etc... Will move forward 1 or 2 in a For Next loop.

Step with a negative number after: Step -1 or Step -2 etc... Will move backward 1 or 2 in the For Next loop.

So if I want skip 2 at a time forward:

For $i = 1 To 10 Step 2
    MsgBox(64, "Info", $i)
NextoÝ÷ ØÈÁ©í¶$µ«bæÚrL­ÛºÚ"µÍÜ   ÌÍÚHHLÈHÝHÙÐÞ
    ][ÝÒ[É][ÝË ÌÍÚJB^

Note the larger integer first in the For next 10 Then 1, Since it's larger first, I use the negative approach demonstrated.
