{p 8 17 2}{cmdab:token:ize} [[{cmd:`}]{cmd:"}][{it:string}][{cmd:"}[{cmd:'}]]
	[{cmd:,} {cmdab:p:arse:("}{it:pchars}{cmd:")} ]


{title:Description}

{pstd}
{cmd:tokenize} divides {it:string} into tokens, storing the result
in {hi:`1'}, {hi:`2'}, ... (the positional local macros).  Tokens are
determined based on the parsing characters {it:pchars}, which default to a
space if not specified.


{title:Option}

{phang}{cmd:parse(}{it:pchars}{cmd:)} specifies the parsing characters.  If
{cmd:parse()} is not specified, {cmd:parse(" ")} is assumed, and 
{it:string} is split into words.


{title:Example}

    {cmd:program define myprog}
	    {cmd:syntax [varlist] [if] [in]}
	    {cmd:marksample touse }

	    {cmd:tokenize `varlist'}
	    {cmd:local first `1'}
	    {cmd:mac shift}
	    {cmd:local rest `*'}
	    {it:...}
    {cmd:end}
