Loop Append File Example AHK

; Example
loop,300
    FileAppend, % "var cat" A_Index " = false`n", my_cat_file.txt

; longer, more human readable way:

myFile := "my_cat_file.txt"
loop,300
{
    thisString := "var cat" . A_Index . " = false`n"
    FileAppend, %thisString%, %myFile%
}
thisString:=myFile:=""

; To create variables dynamically in loop

loop,300
    cat%A_Index% := 0 ; 0 = False
