I have a syntax error in an operation! Give me a tiny help, please!

[Rhazz]

Hello! I have a "syntax error" but I can't understand where is it. Can you help me with this?

There is two text files. I want to write three lines of the first file in each line of the second file. Then, if the first file has 600 lines, the second file should have 200 lines.

I hope I have explained well what I want.

#include <File.au3>
Local $sFile1
$sFile1 = "File1.txt"
Local $sFile2
$sFile2 = "File2.txt"
Local $sThreeLinesIntoOne
FileOpen($sFile1,0)
FileOpen($sFile2,2)
For $i In ( _FileCountLines($sFile1) / 3 )
   For $a = ( ( $i - 1 ) * 3 ) + 1 ) To ( $i * 3 )
   $sThreeLinesIntoOne = $sThreeLinesIntoOne & FileReadLine($sFile1, $a)
   Next
FileWriteLine($sFile2, $sThreeLinesIntoOne)
Next
FileClose($sFile2)
FileClose($sFile1)

AutoIt returns:

error: syntax error
For $a = ( ( $i - 1 ) * 3 ) + 1 )

You missed an opening parentheses

For $a = ((( $i - 1 ) * 3 ) + 1 ) To ( $i * 3 )

You missed an opening parentheses

For $a = ((( $i - 1 ) * 3 ) + 1 ) To ( $i * 3 )

 

hahaha I was thinking that the error should be a tiny mistake... but my brain is out for today haha Thanks!

But now I have another error:

Variable must be of type "Object".:
For $i In ( ( _FileCountLines($sFile1) )  / 3 )

I didn't found the solution... and today I'm going to get crazy... sorry for my questions >.<

Variable must be of type "Object".:
For $i In ( (_FileCountLines($sFile1))  / 3 )
For $i In ( (_FileCountLines($sFile1))  / 3 )^ ERROR

Did you read HelpFIle TWICE , or more times ?
Why you are using   "For .. in ... next"    for   normal loop ?
 

btw.
your expression:

( (_FileCountLines($sFile1))  / 3 )

again missed one opening bracket.

( ((_FileCountLines($sFile1))  / 3 )

No, I didn't forget a parenthesis. You placed in your code four opening parentheses and three closing parentheses.

And yes, I have read the help file but I'm newbie on AutoIT, and I'm here to learn and improve my programing skill.

I haven't understood why it's wrong to use a "for" loop in my code, sorry!

Rhazz,

As explained in the Help file, you should only use the "For...In...Next" type of loop when dealing with a collection (an Object or an Array). In this case you are using an integer - and so you get an error, again explained in the Help file. Do it like this:

For $i = 1 To (_FileCountLines($sFile1) / 3 )

as the "For...To...Next" loop expects number bounds.

Yes, I had misunderstood that part :s

With "For...To..Next" it works, thanks!

I'm reading the Help File for all of the things that I want to do haha and sometimes I make stupid mistakes xD

We learn from mistakes
It is a pity that often on their own
