Help with checking to see if a function executed or not...

This script is being written to wipe a bunch of temp directories in SAFE mode. My problem is that I'm having a hard time instituting error checking... the script actually works but the messages are misleading and I want them to be accurate. Case and point: the second DirFileWipe() called wipes the temp folder under C:\Windows\Temp but when I'm logged in as a normal user and the script gets access denied, my script still reports as executing successfully. Can anyone suggest how to implement error checking to account for that? @ERROR doesn't seem to be reporting anything... =/
Code:
Break ON
$ = SetOption("WrapAtEOL","ON")
? "!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
? "!! ENSURE THIS SCRIPT IS BEING RUN FROM SAFE MODE !!"
? "!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!" + @CRLF
? "Determining OS Type... "
SELECT
CASE @PRODUCTTYPE = "Windows XP Home Edition" OR @PRODUCTTYPE = "Windows XP Professional"
? @PRODUCTTYPE + @CRLF + @CRLF
$path = %SystemDrive% + "\Temp"
DirFileWipe($path)
$path = %WinDir% + "\Temp"
DirFileWipe($path)
CASE @PRODUCTTYPE = "Windows 2000 Professional" OR @PRODUCTTYPE = "Windows 2000 Server" OR @PRODUCTTYPE = "Windows 2000 Domain Controller"
? "This script is only configured for Windows 2000/XP"
ENDSELECT
Sleep 15
EXIT
function DirFileWipe($path)
IF EXIST ($path)
? "- Wiping temp folder: " + $path
$DirList = DirList($path,4+2+1)
FOR EACH $x in $DirList
? @ERROR
DEL $x /h
NEXT
$DirList2 = DirList($path,4+2+1)
FOR EACH $x in $DirList2
SHELL "%COMSPEC% /c RD /S/Q $x"
? @SERROR
NEXT
? "- $path was wiped successfully..." + @CRLF
ELSE
? "- $path did not exist..."
ENDIF
endfunction
function dirlist($dirname, optional $options)
dim $filename, $counter, $filepath, $mask
dim $list, $sublist, $subcounter
$counter=-1
$dirname=trim($dirname)
if $dirname=''
$dirname=@CURDIR
endif
if right($dirname,1)='\'
$dirname=left($dirname,len($dirname)-1)
endif
if getfileattr($dirname) & 16
$mask='*.*'
else
$mask=substr($dirname,instrrev($dirname,'\')+1)
$dirname=left($dirname,len($dirname)-len($mask)-1)
endif
redim $list[10]
$filename=dir($dirname+'\'+$mask)
while $filename<>'' and @ERROR=0
if $filename<>'.' and $filename<>'..'
select
case (getfileattr($dirname+'\'+$filename) & 16)
if $options & 1
$counter=$counter+1
if $options & 2
$list[$counter]=$dirname+'\'+$filename+'\'
else
$list[$counter]=$filename+'\'
endif
endif
if ($options & 4)
$sublist=dirlist($dirname+'\'+$filename+'\'+$mask,4)
if ubound($sublist)+1

for $subcounter=0 to ubound($sublist)
$counter=$counter+1

$list[$counter]=$dirname+'\'+$filename+'\'+$sublist[$subcounter]
else
$list[$counter]=$filename+'\'+$sublist[$subcounter]
endif
next
endif
endif
case ($options & 2)
$counter=$counter+1
$list[$counter]=$dirname+'\'+$filename
case 1
$counter=$counter+1
$list[$counter]=$filename
endselect
if $counter mod 10
redim preserve $list[$counter+10]
endif
endif
$filename = dir('')
loop
if $counter+1
redim preserve $list[$counter]
else
$list=''
endif
if $mask<>'*.*' and ($options & 4)
$filename=dir($dirname+'\*.*')
while $filename<>'' and @ERROR=0
if $filename<>'.' and $filename<>'..'
if (getfileattr($dirname+'\'+$filename) & 16)
$sublist=dirlist($dirname+'\'+$filename+'\'+$mask,4)

You can clean up your code quite a bit with:
Code:
IF INSTR(@PRODUCTTYPE,"XP") OR INSTR(@PRODUCTTYPE,"2000")
? @PRODUCTTYPE + @CRLF + @CRLF
$path = %SystemDrive% + "\Temp"
DirFileWipe($path)
$path = %WinDir% + "\Temp"
DirFileWipe($path)
ELSE
? "This script is only configured for Windows 2000/XP"
ENDIF
With your original SELECT statement, it will never touch 2000 Systems.
Of course with more than two conditions, you can go back to the SELECT..CASE..ENDSELECT.

Ok, here is the meat of the revised script:
Code:
Break ON
$ = SetOption("WrapAtEOL","ON")
? "!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
? "!! ENSURE THIS SCRIPT IS BEING RUN FROM SAFE MODE !!"
? "!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!" + @CRLF
? "Determining OS Type... "
IF INSTR(@PRODUCTTYPE, "XP") OR INSTR(@PRODUCTTYPE, "2000")
? @PRODUCTTYPE + @CRLF + @CRLF
$path = %SystemDrive% + "\Temp"
DirFileWipe($path)
$path = %WinDir% + "\Temp"
DirFileWipe($path)
ELSE
? "This script is only configured for Windows 2000/XP"
ENDIF
Sleep 15
EXIT
function DirFileWipe($path)
IF EXIST ($path)
? "- Wiping temp folder: " + $path
$DirList = DirList($path,4+2+1)
FOR EACH $x in $DirList
DEL $x /h
NEXT
$DirList2 = DirList($path,4+2+1)
FOR EACH $x in $DirList2
SHELL "%COMSPEC% /c RD /S/Q $x"
? @SERROR
NEXT
? "- $path was wiped successfully..." + @CRLF
ELSE
? "- $path did not exist..."
ENDIF
endfunction
In my DirFileWipe() function, how could I run a check on the passed directory to see if I had the ability to scan it.
IF $DirList <> 0 doesn't evaluate correctly. Looking back at that UDF, I didn't see it reporting error codes on success or failure. Any thoughts?

Assuming that the UDF returns error codes, you need to check immediately after the function call, i.e.:
Code:
$DirList2 = DirList($path,4+2+1)
If @ERROR
; Error reporting here.
Else
FOR EACH $x in $DirList2
...
Next
EndIf
There is one error that you might get back which is a "no more items" style error - this is not an error condition, it just means that the directory enumeration reached the end of the list so you should ignore it.
