#  These procedures generate sequences of results.
#  
#       hex()          sequence of hexadecimal codes for numbers
#                      from 0 to 255
#  
#       label(s,i)     sequence of labels with prefix s starting at
#                      i
#  
#       octal()        sequence of octal codes for numbers from 0 to
#                      255
#  
#       star(s)        sequence consisting of the closure of s
#                      starting with the empty string and continuing
#                      in lexical order as given in s
