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.
