The problem has just disappeared, all of a sudden, even though the code is
now as it was. I have to suspect user error. :-)
I did note in my wanderings that the compiler sometimes has two loop
variables, one for its while and the other for your for. Hardly makes for
efficient code. How hard could it have been to add a for construct to the C
rubbish ?
I have another curly one that I have been meaning to post the code.
