Subject: MI-L sleep or wait function in mapbasic

I want my MapBasic to sleep or wait for a couple of seconds to allow
another Windows program to do something. I've tried a MapInfo Knowledge
Base suggestion, but it hogs the processor and slows down the other
program. That means I have to allow a very long wait so the other program
can finish its work. I've invented an alternative using the Windows API
call Sleep, which doesn't hog the processor. I was wondering whether anyone
knew whether its OK to call Sleep, before I send the MBX out to my
customers...

The MapInfo Knowledge Base suggestion is this

Declare Sub Wait(byVal iSeconds as Integer)

Sub Wait(byVal iSeconds as Integer)
   Dim iEnd as Integer

   iEnd = Timer() + iSeconds
   Do while Timer() < iEnd
     ' whatever
   Loop
End Sub

But the trouble is that the Do-While loop hogs the processor. My
alternative is below. The Sleep call takes the time to sleep in
milliseconds. I'm mainly a Visual Basic programmer, and my VB bible for the
API says Sleep is fine to use with VB. It seems to work with MapBasic too.

Declare Sleep lib "kernel32" (byval Milliseconds as Integer)
Declare Sub Wait(byVal iSeconds as Integer)

Sub Wait(byVal iSeconds as Integer)
    ' Use the Sleep API call to put this thread to sleep without hogging
the processor
    call Sleep(iSeconds/1000)
End Sub

Thanks in advance

Mark
