Keren,
You have a lot of extra spaces floating around in your commands. As far as
I know, when you're inserting script variables into a command in a grads
script, you need to be very explicit with the formatting of the command. In
other words, the spaces around your 'lat', 'lon', 'xloc', and 'yloc' may be
causing the syntax error. I recommend removing those spaces and trying
again. For example, change
"draw mark "flag " "xloc " "yloc " 0.1"
into
"draw mark "flag" "xloc" "yloc" 0.1"
