    <p>I have a nested switch statement inside a switch statement. I am wondering if it is possible to grab the un-nested current item within the scope of the nested switch statement. I know I can accomplish this with a for loop with moderate difficulty but I am hoping there is some elegance I am missing to accomplishing this with switch statements. Below I am try to build some argument processing for one of my scripts.</p> <pre><code># Process Args $currentArg $recurseOn = $false :ListArgs switch -regex ($args) { "-ou?" { $currentArg = "Organizational Unit"; write-host "Noticed ou switch"} "-li?k?e?" { $currentArg = "Compare To"; write-host "Noticed like switch"} "^-re?c?u?r?s?e?$" { $recurseOn = $true; write-host "Recurse switched on..."} default { :CurrentSwitch switch ($currentArg) { "Organizational Unit" { $OU = $_.$_ ; write-host "OU changed to '$($OU)'..."} "Compare To" { $Match = $_.$_ ; write-host "Lookup changed to '$($Match)'..."} } } } </code></pre> <p>I know the present model of $<em>.$</em> does not work but I am looking for something that could refer to the current item. I am thinking I could have a filler variable that I just fill with the current item regardless of condition and use that within the scope, but maybe there is something more elegant. I have also tried labeling my switch statements and attempted 'ListArgs.$_' to no avail.</p> <p>Any input would be much appreciated. Thanks in advance!</p> <p>I did this after posting: </p> <pre><code> # Process Args $currentArg $recurseOn = $false :ListArgs switch -regex ($args) { "-ou?" { $currentArg = "Organizational Unit"; write-host "Noticed ou switch"} "-li?k?e?" { $currentArg = "Compare To"; write-host "Noticed like switch"} "^-re?c?u?r?s?e?$" { $recurseOn = $true; write-host "Recurse switched on..."} default { $item = $_ :CurrentSwitch switch ($currentArg) { "Organizational Unit" { $OU = $item; write-host "OU changed to '$($OU)'..."} "Compare To" { $Match = $item; write-host "Lookup changed to '$($Match)'..."} } } } </code></pre> <p>And was able to get it working, but any input on $_ or loop labels would be appreciated. Or is there a better way to do arg processing in PowerShell?</p>

    1. COI think you've answered your own question. `$item = $_` is how I would do it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
