  Why not pull things from the OBEX, or from the Propeller Tool example library, then tweak, observe, wash, rinse, repeat?

  I'm sure there are theoretical ways to go looking for help, but I don't want to search through all of those things, who knows if I'd find the answer and how long it would take? The quick reference could be an all in one inclusive resource. It's challenging enough trying to turn psuedocode into code, and design hardware, (especially when you are new to this) without having to search through 4 + different locations, hoping you'll find something remotely close to what you want to do, to be able to learn from/tweak/modify it.
  
  I've been trying to find a thorough, but simple example of an if, elseif, elseif, elseif, elseif, else statement for days and have nothing.

  I have to ask, if it has taken days to find the answer coded as sample code, wouldn't it then make sense to write a few "blink the led, if" test cases?
  
  Could all be sorted in an hour or two, with the bonus of you knowing the score, and having nice template code for later!
  
  Are you using the latest Propeller Tool download? It's version 1.2.6.
  
  The manual included has a great breakdown of the various commands, with sample code included.
  
  So, I opened this reference, used the bookmarks on the side to locate if, then using else with if. That got me to page 115, where the following code example exists:
  
  

  if X > 100 'If X is greater than 100
        !outa[noparse][[/noparse]0] 'Toggle P0
  else 'Otherwise,
    if X == 90 'If X = 90
        !outa 'Toggle P1
  
  

  
  
  
  There is also this form, on the same page:
  
  

  if X > 100 'If X is greater than 100
      !outa[noparse][[/noparse]0] 'Toggle P0
  elseif X == 90 'Else If X = 90
      !outa 'Toggle P1
  elseif X > 50 'Else If X > 50
      !outa 'Toggle P2 
  
  

  
  
  
  Following this, there is a nice discussion about potential logic traps, and a recommendation to consider the IFNOT form as well.

  IIRC, isn't there an example of the if statement in the manual which can be launched from the PropTool.

  Yep, the manual is the better reference tool now. The first edition was tough to navigate, but all has been nicely improved in the current version. I use it constantly.

  I'll try that tomorrow?
  
  For some reason on mine when I add a second elseif statement, I can't even compile the code to my eeprom, at least now I have something to go off of, thank you
  
  I've been trying to fool around with some simple blink led code tests, spin is just not intuitive and since the syntax is just not something that makes sense to me, it takes forever to try and guess at what it would be?

  Are you talking about page 115 of the prop manual (as referenced above) or something else, and if something else, could yo8 link to it?

  Yes, the prop manual, and it can be launched from the PropTool. Get the latest PropTool V1.2.6 - it is downloaded with this.

  I can't check it at work, as the file hosting sites are blocked, but at home I was able to download it, are you not able to?
