fixed, feels like playing the old adventure game

Yep, I kept saying 'I've been here before -- how'd I get there?!'
'
found another fixer-upper - did a search on " -1 " and one of the results was " Obsolete PBASIC functions "
and it sent me to " PULSE timing "
'
I was looking for a 'true' or 'false' definition, somewhere I read about -1 was one condition and 0 & 1 were the other condition
for some type of logical(?) operation. Will search the forum.

BASIC is a bit schizophrenic on bitwise and logical operators. Expressions are treated as bitwise unless there is a logical operation in the expression.

so 5 AND 7 results in 5 (bitwise)

but 5>3 AND 7 results in 1 (logical)

Don't look at me, this is how BASIC does it, we try to follow conventions not invent them.

So the value of FALSE is 0, but the value for TRUE is anything not 0. Logical operators return 1, but other functions like IO or IN return -1, because the bitwise NOT of 0 is &HFFFFFFFF or -1

C handles this by having explicit logical and bitwise operators. (& bitwise, && logical)

Thanks for the lead on the -1 -- the IO operations use it, and that is what I am doing.
Creating a bit of a 'state machine' based on switch inputs that are mainly momentary.

for the last two days this has happened
go to "home page"http://www.coridium.us/index.html
hover over the "Products" tab , a sub-menu is displayed
When 1) Arm Computer chips OR 2) Arm Ethernet is selected
..........the 'User Guides" at the bottom just loop back on themselves (no apparent change in the webpage)
''
also on the "Compiler" sub-menu -- only the mbed 1768 is listed - not the Teensy or ArchPro
It seems the only way to get to them is to be on the Home Page and look in the "What's new" block and click on the link

[basicchip]

I think I actually saw the loopback on the User Guides but had forgotten about it, I'll fix that

As for the compilers link, I see all 3 listed from both the home page and the product page groups. I am not seeing what you see.

[olzeke51]

Hover over Products tab (on the home page - per my link)
let the sub=menu show up , then click on compiler
... you see the LPC1114, and both mbed 1768 options
**** I am using Chrome browser - did a 'refresh' on the URL ( I assume it then ignores the cache )

[basicchip]

Ok, i see that, but when you hover over compiler dont you see all the choices?

Nope!

What version of Chrome? Maybe needs an update. I see it on mine, both PC and Android.
