Concommand values

Is there any way to make a concommand that can change the speed of the player, in anyway so say if I wanted to make my speed 1000 I could or 15 I could.

ok? but i want to make a concommand that after you put in the name of it you can also put the speed value

Just make a chat command that takes in an argument then.

Yea But this is for setting speeds, I want to make it able for me to change the speed of my player, through the code in Client,Shared or Serverside. So Can Or Can I not make a concommand that can change the speed of my player with any number i put after the command? If so paste an example line.

can a chat command work globally or in my case do a serverside thing and let the shared file get to it ?

PlayerSay is serverside only.
