@ Function

Support for @ function extended cursor addressing codes depends on the selected compatibility mode. Full support (as described in the main @ function topic) is only available in Reality mode. The sections below list the extended cursor addressing codes supported in other compatibility modes.

Note

Codes that are not listed or are marked "Not available" generate a run-time error and return NULL.
The codes to start and stop video effects (flashing, dimmed, underline, bold and reversed) normally switch on or off the effect concerned but do not affect the others. This behaviour can be changed with the CURSOR.ATTRIBUTES environment option.

Select the emulation you require from the drop down list below:
