[gradsusr] How to mark?

[Muhammad Latif]

Dear Grads Users,
I have used the "maskout" function to maskout all the valuesbelow my threshold value and then I have assigned "1" to the non-missing values.Now, I want to mark (with X symbol) the grids having values "1".Does anyone haveany idea/suggestion/script how to do this?
Your kind reply in this regard would be greatly appreciated.
Regards
