Static variables

Static variables are always implicitly local, but differ from locals because their values are remembered between calls. For example:

LogToFile(TextToLog)

{

static LoggedLines = 0

LoggedLines += 1 ; Maintain a tally locally (its value is remembered between calls).

global LogFileName

FileAppend, %LoggedLines%: %TextToLog%`n, %LogFileName%

}

Assume-static mode [v1.0.48+]: A function may be defined to assume that all its variables are static (except its parameters) by making its first line the word "static". For example:

GetFromStaticArray(WhichItemNumber)

{

static

static FirstCallToUs := true ; A static declaration's initializer still runs only once (upon startup).

if FirstCallToUs ; Create a static array during the first call, but not on subsequent calls.

{

FirstCallToUs := false

Loop 10

StaticArray%A_Index% := "Value #" . A_Index

}

return StaticArray%WhichItemNumber%

}
