HI-TECH C Assembly Language
4.3.8.6 SET
This pseudo-op is equivalent to EQU except that allows a symbol to be re-defined. For example
4.3.8.7 DB
DB is used to initialize storage as bytes. The argument is a list of expressions, each of which will be
assembled into one byte. Each character of the string will be assembled into one memory location.
Examples:
Note that because the size of an address unit in ROM is 2 bytes, the DB pseudo-op will initialise a
word with the upper byte set to zero.
4.3.8.8 DW
DW operates in a similar fashion to DB, except that it assembles expressions into words. Example:
4.3.8.9 DS
This directive reserves, but does not initialize, memory locations. The single argument is the number
of bytes to be reserved. Examples:
4.3.8.10 FNADDR
This directive tells the linker that a function has its address taken, and thus could be called indirectly
through a function pointer. For example
tells the linker that func1() has its address taken.
