Table of Parameters
This table shows a summary of the SCUMM V5 opcodes and their parameters in a concise fashion.
Argument types:
- V = variable
- B = byte constant
- W = word constant
- P8 = variable or byte
- P16 = variable or word
- L = list
- J = jump (used by almost all boolean expressions, comparisons) (equivalent to W)
- D = delay; 24-bit constant (only used by delay instruction, strangely enough)
- A = ASCII string, terminated by the following argument ($00, $FF, $FE...)
- A0 = ASCII string, null-terminated
- A1 = ASCII string, $FF terminated
- FF = the hex value $FF, used for terminating some lists, strings etc.
- SO = sub-opcode, variants listed underneath as "opcode$sub-opcode"
- NS = non-standard encoding that cannot be sufficiently expressed in this table
- + = one or more of the preceding argument (parameter bits usually don't matter)
- None = does not take that argument argument
