Hexidecimal is binary, with the bits grouped in fours.

If I understand you, your concern is with the conversion from the numbers in the assembler file to the binary equivalent. The assembler file will be a string of ASCII characters plus spaces and punctuation. It is the job of the assembler to parse the ASCII string and successfully assign the inputs to something meaningful as far as the assembler is concerned.

Using a lookup table is a time honored technique.
Nested if-elseif-else constructs also works.
The switch or case statement is equivalent to both.

That's three different ways -- I'm sure there are more.
