Turning a Character input into a integer.

okay so, first of all thanks for helping, second of all im very new to matlab so please bare with me if my terminology is incorrect/my coding is incorrect.

so...

what i want to achieve is for the user to input a character when prompted, and from that stage turn it into a integer, here's what i have so far, i thought this would work ive had a play with other alternatives but really have hit a loose end so have come here to seek advice? thank you in advance for any feedback you guys give! its much appreciated. Heres's what i have made so far..

    disp('Text will go here...??:')
  input('Type here...','s') 
  UserIn = ans;
  if  UserIn == A;
    A = str2num('1')
  elseif  UserIn == B;
        B = str2num('2')
  else
  end

Just to add, the error i get it..

Undefined function or variable 'A'.

Error in CharToBin (line 38) if UserIn == A;

if UserIn == 'A'

However, the user might have entered multiple characters, so you should use strcmp()

if strcmp(UserIn, 'A')
