[gradsusr] [BULK] Re: opening text file data

Dear Ramaphane, 
As Muhammad has indicated, the script runs. BUT your Objective is to plot the station Locations on the map, with station names. If that is the 
case, you need to open  a file (eg. open model.ctl) to set the environment (so that you don't get the error massage of No scaling environment) and display a variable. The trick I normally use so that I get a blank map is to set cmin a value higher than the maximum value of the variable (there could be a better way of doing this, I hope somebody will point it out). For example I set cmin 10 before diplaying pr variable in model.ctl.
You also need to zoom in your domain using set lat and set lon. 
See attached map(city.png) I have done with the script.
 Hope this will help.
