Octal

ddddddB, where d is any octal digit

• You can use the letter B or b.

• There can be 1 to 11 octal digits (0 through 7).

• 11 octal digits represent a full 32-bit word, with the leftmost digit allowed to be 0, 1, 2, or 3.

• Each octal digit specifies three bit values.

• The last (right most) digit specifies the content of the right most three bit positions (bits 29, 30, and 31).

• If less than 11 digits are present, the value is right-justified—it represents the right most bits of a word: bits n through 31. The other bits are 0.

• Blanks are ignored.

Within an I/O format specification, the letter B indicates binary digits; elsewhere it indicates octal digits.
