dtw(datestring[,jsnumber=kfalse])
Returns the day of the week of a datestring. For JavaScript client-executed code, jsnumber kTrue returns a number rather than a string; in all other cases returns a string unless it is part of a calculation. dtw() assumes Monday is day 1.
Calculate lDate as dtw(dat('May 8 1977'))
# returns 'Sunday'
Calculate lDate as dtw(dat('May 8 03'))+20
# returns 24
Calculate lDate as dtw(dat(dat('May 8 03')+20))
# returns 'Wednesday'
