Series of Variables by name - autohotkey

Question

In AHK script:
Code for finding a value between great numbers of variables above, for one variable:
If (Variable1 = "sin (90°)")
MsgBox Value is reached
How searching by this method between series of variables with different value of number in their names? From Variable5 to Variable15, Variable51 to Variable105, etc.
How modify this code if number from 5 to 15, 51 to 105, or 74 to 117 etc?
number = 5
If (Variable%number% = "sin (90°)")
.............
Is %Variable%number%% acceptable and will works surely?
And here may also be useful Associative Arrays. What is it by simple examples?

Answer 1

Best practice here would probably be to use an array in the first place.
myArray := []
myArray[1] := "bla"
myArray.Push("bla2") ;by using this you don't need to worry about the index number
myArray[3] := "sin (90°)"
myArray[4] := 63456
Loop % myArray.MaxIndex()
{
If (myArray[A_Index] = "sin (90°)")
{
MsgBox Value is reached
}
}
... another example
anotherArray := []
Loop, read, C:\Files\prog.txt
{
If (A_LoopReadLine = "FileRead, OutputVar, C:\Files\prog1.txt")
{
anotherArray.Push(A_LoopReadLine)
MsgBox, An interesting code line was found. And was added to the array.
}
Else If (A_LoopReadLine = "blablabla")
{
anotherArray.Push(A_LoopReadLine)
MsgBox, An interesting code line was found. And was added to the array.
}
Else If (A_LoopReadLine = "some other text line")
{
anotherArray.Push(A_LoopReadLine)
MsgBox, An interesting code line was found. And was added to the array.
}
;Else
;{
; MsgBox, Nothing important was found.
;}
}
Loop % anotherArray.MaxIndex()
{
currentArrayEntry := anotherArray[A_Index]
MsgBox, %currentArrayEntry%
}

Answer 2

In an expression you can use variable expansion to modify the name of the variable to use:
number = 5
If (Variable%number% = "sin (90°)")
.............
But consider using arrays instead.

Answer 3

Is %Variable%number%% acceptable and will works surely?
Not. More right way
% Variable%number%
but it may have a problem.
Possible way is use Var := expression
Variable:= number
may be.
