' This is "DosPrint+.inc"
' It allows to print formatted output to Windows console (CMD).
' Formats supported:
'   [fc,bc] set foreground and background colors (fc/bc are the 0-15 DOS colors)
'--------------------------------------------------------------------------------
' In order to work, the produced .exe needs to have its byte #221 changed to
' CHR$(3), in order to enable console mode. See http://mougino.free.fr/code/
