SX and 16Byte (Word) Variables

Mike W

I have noticed that the BS series chips work very easly with (Word) Variables and numbers larger than 255.

However I am having problems trying to work with·the same·in SX/B. Does the·SX28 have support for 16 Byte variables·and where do I go to find out more about it.

If you do a search, you will find a lot of discussion about just that. I initiated few threads
about just that topic. There are ways of getting around that in SX/B. Look at SX/B IR remote control thread.

SX/B supports native variable types only: byte and bit. The BASIC Stamp synthesizes Word and Nib variables and this adds a lot of complexity internally -- but the BASIC Stamp programmer doesn't see this. The idea behind SX/B is to let you look "under the hood" to learn from the code -- adding 16-bit (again, not native to the SX) variables will add a bunch of complexity and make understanding the code more difficult. That said, we've talked about 16-bit vars and *may* add them at a later date. What you will note is that many SX/B functions that have 16-bit versions in PBASIC have a resolution parameter to allow the successful use of a byte variable.

Mike,
· Look at the 3rd post in this thread. I posted some SX/B code to handle 16 bit variables.
