Introduction and Overview

Since RISC OS 3.5, the icon Exclusive Selection Group (ESG) has been modified slightly. Rather than being applied as a group of 5 bits within the icon flags word, the ESG is now restricted to 4 bits.

Technical Details

Bit 20 of the icon flags is now used to indicate that the value within the icon's text field contains non-reversible data. That is, in territories where the default write direction is right to left, the text within the icon will not be reversed. This is primarily intended for numeric data.
