Progress bar using vertical pipes

[msconfig32]

I was wondering how I could go from a percentage to fill in a series of vertical pipes to &a for that percentage.
Ex. 50% would turn the vertical pipes to &c in the middle of the lines.
&a|||||||||||||||||||||||||&c|||||||||||||||||||||||||

Hopefully I explained this well enough, thanks

You could probably split the percentage in tenths, so there are 10 pipes and you make 1 pipe green every 10% added (ill provide an example sometime later mayhaps)

EDIT:
Here is a (probably) inefficient example of what I mean that you can look at

command percent:
    trigger:
        set {_p} to random number between 1 and 100
        set {_p2} to {_p} / 10
        if {_p2} is 1:
            send "&a█&c█████████"
        if {_p2} is 2:
            send "&a██&c████████"
        if {_p2} is 3:
            send "&a███&c███████"
        if {_p2} is 4:
            send "&a████&c██████"
        if {_p2} is 5:
            send "&a█████&c█████"
        if {_p2} is 6:
            send "&a██████&c████"
        if {_p2} is 7:
            send "&a███████&c███"
        if {_p2} is 8:
            send "&a████████&c██"
        if {_p2} is 9:
            send "&a█████████&c█"
        if {_p2} is 10:
            send "&a██████████"
