  I tried the code you posted with second mail from you (i.e. the one with
main() function).
  Changing the flags of 2nd scale from OPC to NORMAL it was made a usual scale
that worked without any glitches/flaws. I don't get - what is your problem?
Could you demonstrate it using only scales with flag NORMAL? (Give exact
values for step sizes and range)? If you can't - then there is a flaw in math
in pchoct() and other conversion functions.
