beav is an editor for binary files containing arbitrary
data. Text file editors, on the other hand, expect the
files they edit to contain textual data, and/or to be
formatted in a certain way (e.g., lines of printable
characters delimited by newline characters).
With beav, you can edit a file in HEX, ASCII, EBCDIC,
OCTAL, DECIMAL, and BINARY. You can display but not edit
data in FLOAT mode. You can search or search and replace
in any of these modes. Data can be displayed in BYTE,
WORD, or DOUBLE WORD formats. While displaying WORDS
or DOUBLE WORDS the data can be displayed in INTEL's or
MOTOROLA's byte ordering. Data of any length can be
inserted at any point in the file. The source of this
data can be the keyboard, another buffer, or a file.
Any data that is being displayed can be sent to a printer
in the displayed format. Files that are bigger than
memory can be handled.
