    I'm trying to figure out how to write HERALD forms for compiling files
    on Unix.  What does the "logical name" field in a support spec refer to
    on Unix?

Logical names on Unix are found in either of two ways:

(a) Unix environment variables with upper-case names, or

(b) entries in a logical name table internal to T.

The second takes priority.

E.g. you can do "setenv FOO /usr/foo/bar" at the shell before starting
up a T, or you can say (SET (LOGICAL-NAME 'UNIX 'FOO) "/usr/foo/bar")
after starting up a T.  This will be documented and released at some
point.
