I have two shell commands right after each other

To make things simple lets say the old.txt is a static file that doesn’t change and is made already

The first shell with the old.txt info when it runs it makes the old2.txt
Shell "Command.com < old.txt" ‘This line runs and it makes old2.txt file
Shell "Command.com < old2.txt"

The Problem is excel run the command.com Then it runs the command.comBut the old2.txt hasn’t been made yet


What works kind of which I don’t want to use is putting this next couple statements between the two shell “command.com”
Making a for aloop = 1 to 10000000
Next a

What I want to do is change the default of the shell function to have it wait until the shell “command.com” is finished
I think I found on the msn some info on how to do it but I haven’t been able to find that info again
Or maybe if was for a different language
I tried what I remembered it said but I didn’t have any luck


This is some text from help in excel
Note By default, the Shell function runs other programs asynchronously. This means that a program started with Shell might not finish executing before the statements following the Shell function are executed.

Thanks

Did you know Excel offers Filter by Selection?
Add the AutoFilter icon to the Quick Access Toolbar. Select a cell containing Apple, click AutoFilter, and you will get all rows with Apple
Thanks

I quicky looked at his answer before but kind got confused with it
so i didn't understand what all it was doing
but since you pointed it out i read it closer and tried it and it looks like a good solution to my problem
Thanks
