Check for an existing directory

[Frank Ferrell]

Greetings --

Is there a procedure, function or variable that checks for the existance of a directory - for example, C:\TEMP ??

If yes to any or all, would need a return value to invoke creation of a directory unless it already exists.

Greetings Frank!

Frank:

Kind of. In the file "dosunit.bas" found with the installation of PowerBASIC there is a cool FUNCTION called Exist. I wrote a little program to showcase it.

$include "pb35.inc"
     
Test$="c:\temp"
     
if Exist(Test$) = -1 then       'Found!
     
elseif Exist(Test$) = 0 then    'Not found, create directory
 mkdir Test$
end if

I'm actually quite pleased with some of the source code I've been finding with the installation of PB.

Greetings and Thanx Don --

The EXIST feature works just as you said. I'm a little shocked and embarassed that I didn't find it beforehand, as I've used Powerbasic DOS for six years now!
