Given a character in the byte C and a value in V initialized to zero, you need a loop around:

if C >= "0" and C <= "9" then
  V = V << 4 + C - "0"
elseif C >= "A" and C <= "F" then
  V = V << 4 + C - "A" + 10
elseif C >= "a" and C <= "f" then
  V = V << 4 + C - "a" + 10
else
  goto notHex
endif

Are you certain any conversion is needed?

If your $hex numbers represent ASCII values, such as $30 for the character "0", and so forth, then you may need to do a conversion. Same if you need to go the other way, taking $0A and changing it into $3130 or characters "10".

If, on the other hand, you have $0A, for example, representing the number 10, it's already in the form you require. Decimal 10, hex $0A, binary %00001010, are human-readable ways of writing the very same byte of information, and no conversion is in order. Same for anything else that can possibly be in a byte variable. $FF is the same as decimal 255, for example, and represents just another way of writing it on the screen, or on paper, for humans to read. There isn't anything to convert.
