How to know whether a location exists

Guofeng — Wed, 05 Jun 2019 07:54:30 GMT

Is there any function or something in SAS to get the information of a location exists or not.

Like C:\a\d ,d is the folder name.

Thanks,

Use fileexist("path") in a data step.

See https://documentation.sas.com/?cdcId=pgmsascdc&cdcVersion=9.4_3.4&docsetId=lefunctionsref&docsetTarget=n06xm8hwk0t0axn10gj16lfiri43.htm for details.

And while you're at it studying the link @andreas_lds gave you, I advise you to use the navigation pane on the left to see the wealth of functions (see Maxim 9) that SAS provides. You'll also find statements, formats, procedures and whatnot. I know it's a little like reading a phone book, but the more you scan through this, the more you get a feeling for what is there and where it can be found, and that is the gist of Maxim 1.

I also advise you to scroll down to "Learn SAS Programming", and study the "SAS Language Reference: Concepts" there. You'll get a much clearer picture of how the whole thing works, and many questions you have or will have are answered there.
