Assembly Language and
Cross Assembler
Assembly-Language programs are written as source files. They can be
assembled into object files by the Holtek Cross Assembler (HASM). Object
files are combined by the Cross Linker (HLINK) to generate a task file.
A source program is made up of statements, giving directions to the
assembler at assembly time or to the processor at run time. Statements are
constituted by mnemonics (operations), operands and comments.

[optional items]
Syntax elements that are enclosed by a pair of
brackets are optional. For example, the syntax of
the command line is as follows:
HASM [options] filename [;]
In the above command line, options and; are both
optional, but filename is required, except for the
following two cases:
1. Brackets in the instruction operands. In this
case, the brackets refer to memory address.
2. Brackets in the interactive command mode. In
this case, they are message separators.
