[gradsusr] Error using basemap.gs

[sushant puranik]

Hi
I am trying to mask land region with he help of basemap.gs script. So i
adopted following method for masking land

set lat -30 30
set lon 30 100
define ubar=ave(u,t=1,t=20)
define vbar=ave(v,t=1,t=20)
d mag(ubar,vbar)
run basemap.gs L
enable print temp
print
disable print
gxyat -x 1024 -y 840 D:\meanwind1000.png
clear

but after execution of this script it shows
*sh: bash: command not found
Error reading lpoly_lowres.asc*
Hardcopy output file is closed

Since i kept all required files in the script folder including
lpoly_lowres.asc, lpoly_mres.asc, lpoly_hires.asc, opoly_lowres.asc,
opoly_mres.asc and opoly_hires.asc

Anyone know how to use basemap script for masking land?

Thanks in advance


Sushant
