Kwan-yin,
Yeah, I set in my .cshrc as following:
set path=($path/home/fangwen/grads/bin)
setenv GRDDIR /home/fangwen/gads//dat
setenv GASCRP/home/fangwen/grads/lib
now I can open .ctl files with absolute path, but when I "ga->run sample.gs" , it do not work, the error message is : Can't open sample.gs . the sample.gs is just under directory of grads.I tried with absolute path, got the same error. I don't know why. Please help me.
WEN F
