The RS group of commands is a handy way of defining structures:

RSRESET str_pStuff RW 1 str_tData RB 256 str_bCount RB 1 str_SIZEOF RB 0

The example defines four equated symbols:

Defined symbols

Name	Value
str_pStuff	0
str_tData	2
str_bCount	258
str_SIZEOF	259

There are four commands in the RS group of commands:

RS related commands

Command	Meaning
RSRESET	Resets the _RS counter to zero
RSSET constexpr	Sets the _RS counter to constexpr
RB constexpr	Sets the preceding symbol to _RS and adds constexpr to _RS
RW constexpr	Sets the preceding symbol to _RS and adds constexpr*2 to _RS

Note that a colon (:) following the symbol-name is not allowed. RS symbols can be exported and imported. They don't change their value during the link process.
