[ncl-talk] system/systemfunc commands

[M P]

Thanks, the new code and response are below. I also modified the code after
Dave's suggestion
but that does not improve.
I am sorry but that is a bummer,
Mark

(directory "./test" exits)
begin

   ncldir="./test"
   command="cd " + ncldir

   system("pwd")
   system(command)
   print(systemfunc(command))
   system("pwd")

end

..../mapp/ncl
(0)     missing
..../mapp/ncl

begin

   ncldir="./test"
   command="cd " + ncldir + "; pwd"

   system("pwd")
   system(command)
   print(systemfunc(command))
   system("pwd")

end

.../mapp/ncl
.../mapp/ncl/test
(0)     .../mapp/ncl/test
.../mapp/ncl
