I need to get only one digit from a number.
For Example

Code:

SomeVar = 200
X = the 1st digit (2) of SomeVar
Y = the 2nd digit (0) of SomeVar
Z = The 3rd digit (0) of SomeVar

Code:

SomeVar = 200
X := SubStr(SomeVar, 1, 1)
Y := SubStr(SomeVar, 2, 1)
Z := SubStr(SomeVar, 3, 1)

I assume that changing 1 changes the number of diggits
Not that I need it, but it will be good to know, how can I get it backwords ?
200 (0, 0 and 2)

Just flip the order of the second paramater to make it reversed:

Code:

SomeVar = 200 
X := SubStr(SomeVar, 3, 1) 
Y := SubStr(SomeVar, 2, 1) 
Z := SubStr(SomeVar, 1, 1)

Another approach:

Code:

someVar := 200

stringSplit, someVar, someVar

loop % strLen( someVar )
  msgbox % ( a_index = 1 ) ? "X " X := someVar%a_index%
         : ( a_index = 2 ) ? "Y " Y := someVar%a_index%
         : ( a_index = 3 ) ? "Z " Z := someVar%a_index%
         : "" ; <- Snips and ties off the end of sausages.

msgbox % X Y Z
; and or
msgbox % someVar1 someVar2 someVar3

Single chars can also use their own array

*Edit forgot to show the array elements by themselves,
added them in purple. In this case use of vars is actually redundant :mrgreen:

Code:

SomeVar = 200
loop, parse,SomeVar 
{
    var := Chr(a_index + (90-strlen(SomeVar))) 
    %var% := "the " a_index " digit (" A_LoopField ") of SomeVar"
}
ListVars
