Tips
When an ENV command contains a name, that name (system, disc
volume, or subvolume) must appear in a valid format and must
identify a currently available system, volume, or subvolume.
The defaults for the ENV command are the system, volume, and
subvolume in use when you invoked TFORM.
The ENV command can be especially useful when you use the SOURCE
command to read in a file from another location. If that file then reads
in other files from its own location, errors can result if the first file fails
to fully qualify the names of the files it reads. You can avoid “file not
found” errors by setting the environment to that of the first file before
sourcing it in.
