[gradsusr] what does "args" mean in grads

[Farah Ikram]

hi,
i am trying to make a function, the syntax i read in grads manual is
funtion name(args). but it is not clear to me that what does "args" comand
do actually.

i found a script some where it starts with
function add(args)
 temp=subwrd(args,1)
 pr=subwrd(args,2)

i also want to ask what does "subwrd(args,1) command do in grads.

thanks
