Zdoom console command

Is it possible to make a command that activates infinite ammo option (like one of those true or false options)?

sv_infiniteammo 1

Oh, I did it:

]dmflags 2048

heh

alias ammo "give all; wait 1, ammo"
ammo


I have no idea if that is correct. Not that it matters, Spork alredy said the easier (and correct) way.

I just went:

]alias allammo "dmflags 2048"

I would probably do

"bind a dmflags 2048"
