Bigger than a byte

Newzed

The SX/B program I'm working on is generating a number larger than 255.· How do I handle this word-sized variable?· I've tried an array but couldn't make it work.

You got to handle things manually.

Jon, I'm trying read RCTime, so I don't what the values are going to be, and I can't read the result into two variables.· Would I be better off just using a byte variable, and changing the resolution to 4 or 5 or whatever to keep the value·less 255?

Ken, it is being generated by RCTime.· On the BS2P the numbers are plus or minus 1600.

The reason that SX/B's version of RCTIME has a resolution value is to allow the result to fit into one byte.

Not necessary, Ken -- one simply needs to adjust the Resolution parameter. This was added specifically to address this issue. If one needs additional resolution the SX/B output of RCTIME could be modified to handle multi-byte vars (you have to adjust the code and delay timers).

Sid,
If you need more acuracy, you can do RCTIME with a resolution of 4 or 5. Then if the value returned is low, then do RCTIME again without the resolution value (defaults to 1).
