I am doing cross development on MSDOS. I need to write ASM codes for
4-bit uC. But the XASM supplied is not a macro assembler which force
me to type tedious code. I decided to write a preprocessor to
translate Macro codes to the codes defined by the manufacturer. Since
I know nothing about lex and yacc, can you give me a pointer(s) on how
to start writing such utilities (probably with lex and yacc).

Thanks
