I would like to declare some integer constants in Powershell.
Is there any good way to do that?

A:
Use -option Constant with the Set-Variable cmdlet:
Set-Variable myvar -option Constant -value 100
Now $myvar has a constant value of 100 and cannot be modified.

Wow, that's clunky. You have to use Set-Variable to do it, huh?

Yes, there's not unclunky way to do it :)

you can also modify and existing variable with either set-variable (aliased to sv) or by using get-variable (gv) and tinkering with its Options property.

A:
Use
Set-Variable test -option Constant -value 100
or
Set-Variable test -option ReadOnly -value 100
The difference between "Constant" and "ReadOnly" is that a read-only variable can be removed (and then re-created) via
Remove-Variable test -Force
whereas a constant variable can't be removed (even with -Force).
See this TechNet article for more details.
