Goto line in batch file

File one.bat starts 2.bat a batch file in the same directory and when 2.bat is done how can I go back to file one.bat and search for a specific piece of text and start on the x th number that is found x being a number in num.txt a text file in the same directory.

If this isn't clear let me try to show you a snippet of code

@echo off 
Cls 
:: file one.bat
2.bat
Echo I'm back
Pause

@echo off 
Cls 
::2.bat
Echo doing stuff...
Set /a %var%+1>file.txt
Call file one.bat && search for 2.bat and find the one that is x down and continue on next line
:: so that would echo I'm back

I know this can be done with the call command but I am looking for a way to do this without the call command thanks!

Re: Goto line in batch file

There is NO WAY to go to a line that have no label! This is a way to do that (based on a label):

@echo off 
setlocal
if defined return goto %return%
Cls 
echo File one.bat
set "return=Ret1"
2.bat

:Ret1
Echo I'm back
Pause

@echo off 
::2.bat
Echo 2.bat: doing stuff...
Set /a %var%+1
one.bat

Re: Goto line in batch file

Why can't you use the call command? It exists for a reason!

The best solution I can come up with is to allow one.bat to take in a label as a parameter and use a goto to skip there.

:: Valid parameters are the words "one" and "two"
@echo off
setlocal enabledelayedexpansion
cls

if not "%~1"=="" goto :%~1

:zero
echo No parameter was given.
goto :eof

:one
echo Parameter ONE was given.
goto :eof

:two
echo Parameter TWO was given.
goto :eof

Re: Goto line in batch file

Posts and threads with crap, useless, bogus, misleading questions should just be deleted.

The internet is becoming full of them - every tech forum - and they are going to be of absolutely no use to any reader in the future.

I'm officially applying for my curmudgeon badge!

Re: Goto line in batch file

This could be useful if some knucklehead has gone and created a call.bat and stuck it in one of the %PATH% directories or the current directory.

Re: Goto line in batch file

I can't follow the question Shadow Thief, and there's no actual text about the task explaining what it's supposed to do...

This line for example.  What function does it serve?

Set /a %var%+1>file.txt

My rant continues below :

Batch scripting has become such a different field, where questions are asked with bogus information, and there is no discussion about the task, and add to that - the examples you see are made up and don't reflect the actual task.

Programming isn't something that lets you guess what the person wants to do - and batch scripting is most effective, simple and straightforward when it is designed around the real task.

Young programmers don't realise this:
- that information about the exact task allows you and I to write robust and efficient code.
- They aren't aware that they waste the time of people who are helping them free of charge.

Re: Goto line in batch file

@foxidrive: I completely agree with you. When beginners post nonsense questions is a waste of our time trying to understand what they mean. I usually just ignore these questions.

However, now and then these "nonsense" beginner questions include some point that may suggest a new approach or method that may lead to a new or different way to solve a problem. This approach would not even be considered from more experienced users. At least two of my original tricks had emerged from this type of questions, so I consider they as a source of inspiration. Be gentle with they...  ...

In reply to Antonio:

I may have been unreasonably annoyed, as my health is very poor.

I would have liked to have seen some explanation of why call can't be used, as that has a bearing on the final solution.

@foxidrive: I completely agree with you. When beginners post nonsense questions is a waste of our time trying to understand what they mean. I usually just ignore these questions.

I could just ignore them as you wisely suggest - but I'd end up ignoring 90% of the posts.

If I had been clearer in my post I would have commented that a great deal of the time it's not the beginners that do this.

Yes, that's a good point and good advice, thanks.
