The left edge of the offset area displays an arrow whenever the selection begins with an instruction using a PC-relative addressing mode.
The arrow shows where the executing branch instruction will branch to.
The offset display area shows offsets from the start of the resource, or from a previous paragraph start. When editing code, it also displays Macsbug routine names.
The “Decimal Offsets” menu command lets you view offsets in base 10 rather than hex.
This area shows the disassembled code, one instruction per paragraph. You can click on an instruction to select it; click and drag to select a group. Double-click here to select the whole routine.
The Code Editor cannot re-compile assembly language.
This area lets you edit the resource data as hex bytes.
Double-clicking at an offset within the hex selects the paragraph that contains it. If editing code, this will be the entire instruction.
This area displays the data as ASCII text. Normally unprintable characters are displayed as ‘.’ You can type most characters into here.
To enter special unprintable characters, such as a Return or Tab, hold the Option key down while typing.
