ACC SHELL

    Formats and prints ARGUMENTS under control of the FORMAT.
    
    Options:
      -v var	assign the output to shell variable VAR rather than
    		display it on the standard output
    
    FORMAT is a character string which contains three types of objects: plain
    characters, which are simply copied to standard output; character escape
    sequences, which are converted and copied to the standard output; and
    format specifications, each of which causes printing of the next successive
    argument.
    
    In addition to the standard format specifications described in printf(1)
    and printf(3), printf interprets:
    
      %b	expand backslash escape sequences in the corresponding argument
      %q	quote the argument in a way that can be reused as shell input
    
    Exit Status:
    Returns success unless an invalid option is given or a write or assignment
    error occurs.
