how to use confirmdir command

[lamya kejji]

Hi everyone,

I don't know how to use the confirmdir command.
Here is in what I want to use it :

I am double looping over folders containing folders:

year folders 2012 to 2016 and in each year folder there are month folders.
The 2016 folder contains months from January to June.

Now I would like to execute some code after the double loop. But, because when I change directory to July it gives me an error, the code rest of the code is not executed.
I think the command I need is confirmdir but I don't know how to use it.
Could anyone help with this?

Many thanks,

confirmdir (SSC, as you are asked to explain; please do read FAQ Advice 12.1) leaves 0 in r(confirmdir) if a directory exists and 170 otherwise:

. mkdir june6

. confirmdir june6

. ret li

macros:
         r(confirmdir) : "0"

. confirmdir june7

. ret li

macros:
         r(confirmdir) : "170"
