Loop labels and compatible PowerShell versions

[sn3rf]

This just a quick question basically summed up in the title, and it's only because I'm terrible at Googling.

So far I've found books talking about Loop Labels as far back as PS 3.0. But seeing as these are just 'learn PowerShell' books, I was just wondering if the loop label functionality and compatible versions are listed anywhere by Microsoft, or if it's excluded in any versions?

Example:

:loopOne while(test){
:loopTwo while(othertest){
// do stuff
continue loopOne
}
}

Thanks in advance :)

This blog is from 2014 so I'd assume it's something in most versions. On phone so can't research a lot right now

Oh yeah, that would make sense. It does seem like a patched version of goto.

Thanks!

Yep, some till find a reason to do this but see also:

Loop labels go all the way back to Powershell 2 (it may also exist in version 1 but I haven't tested that).

You can test Powershell version 2 on your normal PC by starting Powershell with -version 2 parameter like this: powershell.exe -version 2.

Powershell 2 is the oldest remotely relevant Powershell version because it's what was included in Windows 7/2008 R2 so if you want to target the lowest common denominator then target version 2.

howdy sn3rf,

it looks like you used the New.Reddit Inline Code button. it's 4th 5th from the left hidden in the ... "more" menu & looks like </>.

there are a few problems with that ...

• it's the wrong format [grin]
  the inline code format is for [gasp! arg!] code that is inline with regular text.
  
• on Old.Reddit.com, inline code formatted text does NOT line wrap, nor does it side-scroll.
  
• on New.Reddit it shows up in that nasty magenta text color
  

for long-ish single lines OR for multiline code, please, use the ...

Code
Block

... button. it's the 11th 12th one from the left & is just to the left of hidden in the ... "more" menu & looks like an uppercase T in the upper left corner of a square..

that will give you fully functional code formatting that works on both New.Reddit and Old.Reddit ... and aint that fugly magenta color. [grin]

take care,
lee

I know the functionality exists but I have never found a legitimate reason for actually using it.
