It doesn't, unfortunately, since the original code doesn't
use that (duff) bit of syntax. I hurredly produced the
simple subset program - I am, after all, supposed to be
working :) The line is completely redundant anyway so removing
it should produce a better minimum subset - my apologies.
The sysread() must(tm) be doing the right thing, since the
length of the string is tested on the next line, and is correct. Again the sysread is used
only to guarantee maximum "simpleness" for this example; it isn't actually what happens in the program itself.
Take is as read that these two aspects don't impact on the problem.
Cheers for responding,
Mike.
