"powershell is not a programming language"

I think the OP means Power Shell Scripting Language which is one.

The inevitable example:

[int]$i = 99;
for($i=99; $i -gt 0; $i--) {
    write-host $i  " bottles of beer on the wall";
    write-host $i  " bottles of beer";
    write-host "Take one down, pass it around"
    write-host ($i-1) " bottles of beer on the wall"
    write-host ""
}
