Hi

Didnt find this anywhere.
What's the equivalent to :

command
command

:labelx

I believe labels are only used in conjunction with the loop terminators: break and continue. For example:

uter while (1) {
while (1) {
break outer
}
# break without label would break to this line
}

Note that the label in "break <label>" doesn't have to be a literal/constant string. It can be an expression (found this little tidbit in Bruce Payette's book Windows PowerShell in Action) e.g.

$target = "outer"
uter while (1) {
while (1) {
break $target
}
}

Your code above looks kind of like batch script. I would probably modify it to use some form of control flow e.g.:

if (<some expression>) {
# skips this block of commands if <some expression> doesn't evaluate to $true
command
command
}

Along with what Keith Said... before Powershell I wrote a good bit of Batch
scripts... in Powershell I have yet to find any reason for the Label.
Controlling script execution in Powershell is WAY easier than batch (once
you get use it to it.) I would recommend biting the bullet and forcing your
self to rethink script design.

for exeption handling the labels are handy (and breaking nested loops )
