Trying to use the peek command but theres no word for it.

I'm guessing to use PeekInt() to get a word, I'm not sure.

How many bytes do you want to read:

peekbyte, peekshort or peekint are all useful...

dman	(Posted 2011) [#3]

trying to peek a word not a byte, rather two bytes.

Two bytes -> PeekShort().

thanks for the info, I appreciate the help.

one thing, about the FOR loop, the step command only takes constant values. How can I use a assigned variable? ex.

range = 12

FOR b=0 TO length STEP range

You can't, you'll have to redesign the loop as a While or Repeat.

b = 0
While b <= length    ;Shouldn't this be < ?
    ...
    b = b + range

It should be just "<" if you're starting from 'zero' (and you are: "b = 0").

If you started at '1' then you can let it get to the 'length' (which is always 1-based as well).

Also, you can use this:

const range=12
For b=0 to length STEP range

Or this:

For b_=0 to length/range b=b_*range

What I do often is to run for..next as normal:

For k=1to 10
Next

And then judt throw in k*range wherever k effexts what happens. Equivalent to "1to 10 Step range".

Also, this:

For b=0 to length
  print b
  b = b + range-1
Next
