Here there - here’s the first three digits;

[lua]local path = system.pathForFile( “myFile.txt”, system.DocumentsDirectory )
local file = io.open( path, “r” )
if file then
data = file:read( “*n” )
print( “data”…data )
io.close( file )
end

numberString = tostring(data)
threeDigits = numberString:sub(1,3)
print (threeDigits)[/lua]

And here’s the last three;
[lua]local path = system.pathForFile( “myFile.txt”, system.DocumentsDirectory )
local file = io.open( path, “r” )
if file then
data = file:read( “*n” )
print( “data”…data )
io.close( file )
end

numberString = tostring(data)
threeDigits = numberString:sub(7,9)
print (threeDigits)[/lua]

Hope this helps :slight_smile:
