This chapter identifies the directives and special characters that must be recognized by SC100 assemblers.
Directives are commands that instruct the assembler to carry out some action during assembly, rather than
instructions to be directly translated into object code.
A detailed description of the SC00 Assembler, its syntax, and directives can be found in the SC100
Assembly Language Tools User’s Manual.
6.1 Assembler-Significant Characters
Several one- and two-character sequences are significant to the assembler. Some have multiple meanings
depending on the context in which they are used. These characters are as follows:
;
;;
\
?
%
^
"
@
*
++
[ ]
<<
<
>
#
