Action name: OpOctalThis command makes the current instruction or data operand type octal. IDA always uses 123o notation for octal numbers even if the current assembler does not support octal numbers.
When you use this command, IDA deletes the manually entered operand.
If the cursor is on the first operand (the cursor is before ',') then the first operand will be affected; otherwise, all other operands will be affected.
