# Draw a single line of ASCII text using the built-in font (GNU unifont)
# Also demonstrates bounds-checking _before_ drawing.
#
# To build a disk image:
#   ./translate ex5.mu             # emits code.img
# To run:
#   qemu-system-i386 code.img
# Or:
#   bochs -f bochsrc               # bochsrc loads code.img
#
# Expected output: text in green near the top-left corner of screen
