How to Use ENV
When you specify a file name with one of the FILE commands or a
SOURCE command and do not fully qualify it (provide the system name,
volume name, and subvolume name as well), TFORM automatically
expands the file name so it contains all four parts of a fully qualified
GUARDIAN 90 file name. By default, TFORM uses the names of the
default environment—the system, volume, and subvolume in effect when
you invoked TFORM—to expand a simple file name. If the file name is
located outside the default environment, use the ENV command to tell
TFORM how to expand the file name into a fully qualified GUARDIAN 90
file name.
ENV SYSTEM Option
ENV SYSTEM \ system-name gives TFORM the system name for
subsequent expansion of the file name you specify.
ENV SYSTEM with no system-name resets the system name to
whatever name was in effect at the time you started TFORM.
ENV VOLUME Options
ENV VOLUME with no modifier resets the disc volume name and
subvolume name to whatever names were in effect at the time you
started TFORM.
ENV VOLUME $ volume-name
This command gives TFORM the disc volume name for subsequent
expansion of the file name you specify.
ENV VOLUME $ volume-name.subvolume-name
This command gives TFORM the volume name and subvolume
name for subsequent expansion of the file name you specify.
ENV VOLUME subvolume-name
This command gives TFORM the subvolume name for subsequent
expansion of the file name you specify.
