The READ intrinsic reads an ASCII string from $STDIN
into an array.
This is similar to calling the FREAD intrinsic against the
file $STDIN. READ is intended as
a quick method of obtaining input from the terminal for temporary
programming. Read timers or timeouts must be set prior to calling
READ by first calling FCONTROL using the appropriate controlcode
values.
When you use the READ intrinsic, the full capabilities of
the file system are not available to you. For example, since no
file number can be specified in the call it is not possible to use
the :FILE command to redirect input for programs
using READ. (The only way that input can be redirected is to use
the $STDIN=filename
option of the :RUN command.) Input always comes
from the $STDIN file opened by
the session at logon time.
READ differs from READX in how it interprets an end-of-file.
READ reads a record and, if there is a colon in the first column,
end-of-file is set.
