ENGLISH n. The source code for a program, which may be in any
language, as opposed to BINARY. Usage: slightly obsolete, used mostly
by old-time hackers, though recognizable in context. At MIT, directory
SYSENG is where the "English" for system programs is kept,
and SYSBIN, the binaries. SAIL has many such directories, but the
canonical one is [CSP,SYS].
