# Example reading commandline arguments: compute length of first arg.
#
# To run:
#   $ subx translate ex9.subx ex9
#   $ subx run ex9 abc de fghi
# Expected result:
#   $ echo $?
#   3  # length of 'abc'
#
# At the start of a SubX program:
#   argc: *ESP
#   argv[0]: *(ESP+4)
#   argv[1]: *(ESP+8)
