what this(+=) operator combo do?

i saw this in Hawk552 gamestatus2.
heres some code:

Pos += format(g_HudMessage,sizeof g_HudMessage - 1,"Game Status^n")

count++

its the same as doing

count = count + 1

in this case it adds the string to pos with out having to reassign it

another way would have been
pos = pos + format(...)

ok help me understand this now.

so i have variable Pos

new Pos

ok then i format a string with this

format ( output[], len, const format[], ... )

im passing in a array g_HudMessage then i dont know whats sizeof
is it function inbuilt in pawn like equali?
anyways it looks like im taking away from the message(that follows later) 1 and then Pos what is 0 as it was just declared and then is the message itself.

so output of this format will be some integer that will be added on to Pos

right?

PHP Code:

new g_HudMessage[32]

new Pos = format(g_HudMessage, 31, "Hello %s", "World")
// Or
new Pos = format(g_HudMessage, sizeof(g_HudMessage) - 1, "Hello %s", "World") 


"Pos" is an integer. And, format() outputs the number of characters that were copied to the string "g_HudMessage". So in this case "Pos" is 11.
