Returns the Nth token or amount of tokens in string.
$gettok(string,N,C)
Where N is the Nth token you wish to be returned from string by delimiter C. Alternatively N can be given as 0 to return the amount of tokens in string
Examples
$gettok(Ave:IT,1,58) ;returns Ave
This returns the first token using $chr(58) as the delimiter
$gettok(Ave:IT,0,58) ;returns 2
This returns the value 2 because there is two values when delimited by $chr(58)
Note: N can be a range N1-N2, Example:
$gettok(Word1 Word2 Word3 Word4,2-3,32) ;returns Word2 Word3 $gettok(Word1 Word2 Word3 Word4,-2-1,32) ;returns Word3 Word4
The second example would return the second token from the end until one token from the end.
