# The Symbol Guide
|
||
|
|
|
||
|
|
The following prefixes are really special,
|
||
|
|
and are lexcrunch's responsibility:
|
||
|
|
|
||
|
|
"$$THING" : These are defines.
|
||
|
|
"$Thing" : Writes a global into stream. If not already allocated, is allocated a global.
|
||
|
|
|
||
|
|
"$NT|THING" : Allocates THING from temp pool
|
||
|
|
"$DT|THING" : Returns temp THING to temp pool
|
||
|
|
|
||
|
|
"$NA|THING1|THING2" : Copies $THING2 to $THING1 in forwards table (not in backwards table)
|
||
|
|
"$DA|THING1" : Removes THING1 in forwards table.
|
||
|
|
|
||
|
|
"${" : Opens a frame.
|
||
|
|
"$}" : Closes a frame. (Attached temps are released.)
|
||
|
|
"$L|THING" : Allocates THING from temp pool, attaches to stack frame, writes to stream.
|
||
|
|
|
||
|
|
The rest are convention:
|
||
|
|
"$iThing" symbols are Installer Wrapper.
|
||
|
|
"$icThing" symbols are Installer Core.
|
||
|
|
"$dfThing" symbols are DEFLATE Engine.
|
||
|
|
"$bdThing" symbols are BDIVIDE Engine.
|
||
|
|
|
||
|
|
"$a0", "$a1", etc. are Local Symbols.
|
||
|
|
THESE ARE AN OLD MECHANISM, USE FRAMED TEMPS INSTEAD.
|
||
|
|
These are reserved only for use in locals.
|
||
|
|
(For loops count.)
|
||
|
|
|
||
|
|
"$lThing" symbols are used to name Local Symbols using aliases.
