tab(-10,AG_TABWRAPPER); chr(#); ... ; chr(127);)
AG_TABWRAPPER (117) is used to wrap 'problematic' TAB(-1,#) commands for delivery to the client without interfering with the screen tracking logic on the server side. May be used with any TAB(-1,#) command, but is mainly useful with the mouse cursor TAB commands that are followed by raw data bytes, e.g. TAB(-1,158), TAB(-1,160) and TAB(-1,162).

Comments
In general, to convert from:
TAB(-1,#); <trailer bytes>;
use:
TAB(-10,AG_TABWRAPPER); chr(#); <trailer bytes>; chr(127);
Example
The equivalent of:
TAB(-1,158); "C"; chr(34); chr(27); chr(30);
is:
TAB(-10,AG_TABWRAPPER); chr(158); "C"; chr(34); chr(27); chr(30); chr(127);
Or, as an alternative to AG_SETCURSOR, you could replace TAB(-1,160); chr(#) with TAB(-10,AG_TABWRAPPER); chr(160); chr(#); chr(127);
