Eight bits of binary
data represent the code for one digit of character data. Therefore,
you need at least three digits of octal data to represent one digit
of character data, which includes an extra bit. $OCTALw.
treats every three digits of octal data as one digit of character
data, ignoring the extra bit.
Use $OCTALw.
to read octal representations of binary codes for unprintable characters.
Enter an ASCII or EBCDIC equivalent for a particular character in
octal notation. Then use $OCTALw.
to convert it to its equivalent character value.
Use only the digits
0 through 7 in the input, with no embedded blanks. $OCTALw.
ignores leading and trailing blanks.
