[JASS] "Variable length is uninitalized"

[TwoLeft]

Why is this happening and how to fix it?

Does the StringLength() function not do what you want?

local string s = "test"
local integer length = 0
set length = StringLength(s)
// length = 4

The integer variable length is uninitialized, which means that it doesn't have any value. Just initialize the length variable to 0.

pjass unfortunately displays the error on the wrong line. It's the line set length = length + 1. You didn't assign any previous value to it and reading an uninitialized variable would abort the execution.

Alright, thanks for the answers!
