Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I thought I knew how to do binary IO, but I guess not.

This simple program:

option default integer
option base 1

const BLEN = 10
const DSIZE = BLEN*64

dim b(BLEN) = (0, 1, 2, 3, 4, 5, 6,7 ,8 ,9)
save data "bfile.bin" peek(VARADDR, b()), DSIZE
end

..dies with 'address error'.

I am sure many of you can and will point out the noob error.
Thanks!

I should have added that this is run on a CMM2 Gen2 with MMBASIC v 5.07

I think you have 3 errors
1: no comma between the filename and the address
2: comma in the peek function which shouldn't be there
3: you are saving 8* too much data - try BLEN*8

LOL, thanks, Peter! Actually, the real code does have the comma; I just mis-typed it into the forum. The value 64 is me not thinking straight!
