I have tried using setTimeout to delay the execution of a function with:
setTimeout('fun ction()', ms)
This works, but if the function has parameters:
setTimeout('fun ction(p1, p2, p3)', ms)
it does not work.
Any ideas very much appreciated.

You need to move the parameter variable names out of the string, so they are
interpreted rather than taken literally when the string is passed from the
timeout to the executioner:
setTimeout('fun ction(' + p1 + ', '+ p2 + ', ' + p3 + ')', ms)

simple.
setTimeout(func tion() { myFunc(a, b, c); }, ms);
enjoy.

Bad choice of function name, since "function" is a keyword in Javascript.
I'll call it "theFunctio n" instead.

setTimeout('fun ction(' + p1 + ', '+ p2 + ', ' + p3 + ')', ms)
That only works if the values converts to strings that are literals
representing the same value. That's generally not the case for
objects, nor for strings (i.e., it only works for numbers, booleans,
null and undefined). So, it's *not* a good idea in general.
Using variable names is better, but not much, since the variables need
to be in the scope where the string is evaluated, and that is the
global scope. So 'theFunction(p1 ,p2,p3)' *will* work, *if* p1, p2 and
p3 are the names of global variables.
The best alternative is to use a function as first argument to
setTimeout:
setTimeout(func tion(){theFunct ion(p1,p2,p3);} , ms);
It works in all modern browsers.

I do think p1,2,3 are certainly names of variables
(this variables modified by main function before re-call to itself)

We can suppose they are not global
if not, I do not understand the why of question ...

that's the best way

is that to say it will not work on my NC4.5 ?

My main question is "Is it possible to get delay less than 1 millisecond in Turbo C"? If by changin any header file (e.g. dos.h) or by creating my own "delay" function, at any way Can I get delay less than 1 millisecond?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
