If you fail after trying all the suggestions then do this. It almost always
works for me:
Open Network Connections
Right-click on your wireless connection
Click Properties
Uninstall Client for Microsoft Networks
You will be asked to boot your PC.
When you get back up, reinstall Microsoft Client for Networks.

Subject: Re: [NF] Language choice from a teachers POV
LOCAL a as int, b as int && optional
accept 'Input a number ' to a
accept 'Input another number ' to b
* ?a + b && try this and work out why it is wrong
? VAL(a) +VAL(b)
** or: **
?a+' plus '+b+' = '+TRANSFORM(VAL(a) +VAL(b))
Demonstrates:
that fox carries a lot of historical baggage (as did Chet's example)
that programming is full of pitfalls
that the people teaching 'computing' are still completely out of touch
with 'real' usage -
Even simple 'real' applications will use a gui and a database of some sort
- so the lesson should be something like:
open up an api
create a form / web document
add two text input boxes - with labels / instructions and an output box
add a command button
write code (discuss where it should be - button, form/document, application
object) to handle the button's click event:
check there is numeric input,
add the two inputs,
display the result in the output box,
and write the three values to a table (discuss how you might read back the
data - introduce the concept of keys).
I am reminded of the true story of a professor of 'computing' who was asked
why he did not teach his students 'commercial' computing. He replied that
he had tried it but it was too trivial - they had done 'invoicing' and all
the students got the right 'answer' (total-cost = unit-price * quantity).
