Further information
1. The specified file path is relative to the working directory of the Mosel instance performing the file operation.
2. File operations are performed under the restrictions of the Mosel instance. For example, if the remote instance does not have write access, this routine will fail to open a file for writing.
3. Just like accessing files from a Mosel model, any I/O drivers supported by the remote instance can be used with this routine. Drivers
"sysfd:",
"tmp:" and
"shmem:" are therefore available.
