MIDI Lab: bytetable

Source code:	bytetable.cpp
Binaries:	[ Windows 95/NT | Linux (Red Hat 5.0) ]

bytetable prints out the decimal-hexadecimal-binary equivalences for each possible bit combination in a byte. It is useful for explaining the MIDI protocol and standard MIDI files.

Here is the command synopsis:

Print a number-conversion table for one byte

Usage: bytetable [-a][-c][-n][-z] number(s)

Options:
   -a = add a column of printable ASCII character equivalents
   -c = add a comma in the middle of binary numbers
   -n = print a table which includes the negative numbers
   -z = fill in empty digits for binary and hex numbers
   --options = list all options, default values, and aliases

Example usage of the bytetable program (click on the command to see the output):

> # display a table of dec/hex/binary values for one byte
> bytetable

> # display a table of dec/hex/binary using the signed range
> bytetable -n

> # display a table of dec/hex/binary filling in empty digits
> bytetable -z

> # display a table of dec/hex/binary adding a comma in the binaries
> bytetable -c

> # display a table of dec/hex/binary adding printable ASCII codes
> bytetable -a

Suppose that you want to find the equivalences for the hex number fd, then you could run this command:

> bytetable | grep fd
253	fd	11111101

Or, if you want to know the ASCII code for the letter 'M':

> bytetable -a | grep M
77	4d	1001101	'M'

Or, if you want to know the equivalences for hex value for 0x44:

> bytetable -a | grep ...44
68	44	1000100	'D'

Here are the outputs from all possible command-line option combinations:

bytetable bytetable -a bytetable -ac bytetable -acn bytetable -an bytetable -az bytetable -c bytetable -caz bytetable -cazn

bytetable -n bytetable -nc bytetable -nz bytetable -z bytetable -zac bytetable -zan bytetable -zc bytetable -znc
