Hello,
<p>While writing to an piped shell process from IDL in an unix environment
goes fine, I seem to be unable to read from it. Type conversion errors
all over the place. I'm obviously doing something wrong and IDL help is
not explicit on the subject. What is the preferred way to read the output
from a spawned piped child process?
