From: Gail Rubin <grubin@bbn-spca> Small comments on previous messages about CLI's: LIB$EXECUTE_CLI was an unsupported routine in VMS 2.x and is long gone. In VMS 3.x there is a documented restriction that you cannot SPAWN (or run a program using LIB$SPAWN) from a command file. In practice it isn't quite that restrictive. If the parent's sys$input and sys$output are the terminal OR you explicitly specify the child's input and output to be something like NLA0:, you can get the spawn to work. The problem is when the input or output of the parent are files and nothing explicit for input and output is given for the child process. -- Gail Rubin (grubin@bbn-spca or @bbn-unix)
