SDCC

SDCC is the toolchain used in MSXGL to compile, assemble and link the sources files.

The assembler, sdasz80, is based on ASxxxx cross assembles.

sdasz80 syntax is almost standard except for:

• Define instructions numeral values: must be prefixed with # character.
• Define directive: must be prefix with . character.
• Access to IX and IY register using offset: offset have to be write into parentheses before the register name.
