here's a do-while loop - the contents of the loop are executed BEFORE
the condition is tested.
------------------------------------------------------------------
labelA:
do some loopy things
if (we need to loop again)
goto labelA:
------------------------------------------------------------------

to contrast that, here's a while loop:
------------------------------------------------------------------
labelA:
if (we need to do the loop at all)
{
do some loopy things
goto labelA:
}
------------------------------------------------------------------

Sorry it's in some pseudocode that doesn't really represent a language
at all. I can't produce asterisk's dialplan functions from memory yet!
I'm sure that this will convert very simply though with minor work. "if"
would become "GotoIf".

For the archives, the usage of asterisk's While construct is found at
