Handler behaviour

Sends several CRadiWindowManager::SendMessage calls and branches on application field +0x458 and command flags.

Encoding

The command header is one 32-bit word, as described in §3 Instruction encoding:

 31            24 23            16 15             8 7              0
+----------------+----------------+----------------+----------------+
|  flags         |  argument byte |  extra words   |  0x8A          |
+----------------+----------------+----------------+----------------+

Bits 8–15 give the number of 32-bit operand words that follow. Bits 16–23 are handed to the handler as a bitfield; on character commands bit 0 normally says whether a character selector word is present. Bit 31 is the keep-going bit.

Operand fields

2 documented fields. input fields are read from the command's operand words; derived fields are computed from other fields rather than stored separately.

Field	Role	Meaning
`arg`	input	Raw handler argument byte from the command header. It is printed only when it differs from the value the named fields already imply, so seeing it means the command uses an unusual argument encoding.
`yield`	derived	Pause the script here for one game frame; the next command runs on the following update. Lines without it keep running immediately.

Engine calls

Engine functions this handler was observed calling:

CRadiWindowManager::SendMessage(unsigned int,int,CRadiWindowParamBase*)

Bit masks

Masks the handler applies to its argument byte or operand words:
