Adding Letters To Variables

[Jamie1414]

Hey im having trouble adding a letter to a variable. this is what code i was trying to do it with but failed in doing so...

$command = $command + "y"

if u are wondering, i am using this code to find out what the user is typing for my friends game so i can know what the user inputs in his textbased game. and i got a hotkey for every character, if any1 has a better way to do this plz tell me

u havent defined $command and you cant add letters you would do a & not a +

and if ur trying to figure out that then check out _ispressed in beta
