Programming note: because of the way the REXX interpreters (being used for this example) ensures screen output fidelity, if ninety characters are displayed on a ninety-byte wide screen, REXX apparently forces and extra blank, causing to what appears to be a blank line after the line displayed. Because of this, the last color bar ('''_.8''') has been shorten by one byte.
