0x1C — stand_context

Stand-position/current-context helper. It reads stand-position data, calls GetAbstractionStandPosNumber when an operand requests abstraction resolution, and writes position/posture fields into the current global script context.

Handler behaviour

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   |  0x1C          |
+----------------+----------------+----------------+----------------+

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

8 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
`context`	input	Whether this line sets the stand-position context value. Argument bit 0: Command_1c writes the operand's low bits into bits 0-9 of a global halfword, leaving its upper bits alone.
`context_low10`	input	The context value itself: the low 10 bits of `stand_word`.
`position`	derived	Whether the position fields are written into the current context.
`posture`	derived	Set when a posture operand is included on this line.
`stand`	input	Stand-position operand, resolved through GetAbstractionStandPosNumber.
`stand_position`	input	Stand-position id resolved through GetAbstractionStandPosNumber.
`stand_word`	input	Packed stand-position word; the annotated parts beside it decode it.
`yield`	derived	Pause the script here for one game frame; the next command runs on the following update. Lines without it keep running immediately.
