This routine has the responsibility to determine if a particular dbgprint is going to be printed and ifso to
fiddle with the indent. so the return value is whether to print; it is also used for just fiddling with the indent
by setting the highoredr bit of the mask.
The Mask is now very complicated owing to the large number of dbgprints i'm trying to control...sigh.
The low order byte is the controlpoint....usually the file. each controlpoint has a current level associated
with it. if the level of a a debugtrace is less that then current control level then the debug is printed.
The next byte is the level of this particular call; again if the level is <= the current level for the control
you get printed. The next byte is the indent. indents are only processed if printing is done.
