Be careful when using @ERROR at the start of loops if you don't precede it with the function.
Take this for example, exactly the same procedure run twice:
Code:
$Index = 0
While @Error=0
$KeyName=ENUMKEY("HKEY_CURRENT_USER\Console\", $Index)
If @ERROR = 0 ?
"Name found on first pass: $KeyName"
$Index=$Index+1
EndIf
Loop
$Index = 0
While @Error=0
$KeyName=ENUMKEY("HKEY_CURRENT_USER\Console\", $Index)
If @ERROR = 0 ?
"Name found on second pass: $KeyName"
$Index=$Index+1
EndIf
Loop
The problem is that the second pass will not display any results.
The reason is that @ERROR from the first loop is still set, so that the second loop fails instantly.
In a more complex function this can be a bugger to spot.
The solution is to clear the error status before starting the loop:
Code:
$Index=Execute("Exit 0") ; Initialise index and clear error status
While @Error=0
$KeyName=ENUMKEY("HKEY_CURRENT_USER\Console\", $Index)
If @ERROR = 0 ?
"Name found on first pass: $KeyName"
$Index=$Index+1
EndIf
Loop
$Index=Execute("Exit 0") ; Initialise index and clear error status
While @Error=0
$KeyName=ENUMKEY("HKEY_CURRENT_USER\Console\", $Index)
If @ERROR = 0 ?
"Name found on second pass: $KeyName"
$Index=$Index+1
EndIf
Loop

Spooky. I'll have to type quicker.
