And in fact, the closest approximation of switch/case, currently, would use exactly that: GOTO %switchlabel
Code:

  ;    switch(condition) {
  ;        case 1,2:
  ;                  code here
  ;                  break;
  ;        case 3:
  ;                  code here
  ;                  break;
  ;        case N:
  ;                  code here
  ;                  break;
  ;        else
  ;                  code here
  ;    }                         // End of switch(condition)
 
  if (condition) {
    goto $ifmatch
 
    :1
    :2
    ;  command(s)
    goto EndOf.Switch | ; break
 
    :3
    ;  command(s)
    goto EndOf.Switch | ; break
 
    :N
    ;  command(s)
    ;  Since this is the last section, goto EndOf.Switch is redundant
 
    :EndOf.Switch
  }
  else {
    ;  command(s)
  }

One pass through evaluating the condition and then go directly to the appropriate section of code (which is the benefit of using switch). Switch is a special case of IF-ELSEIF-ELSE where the exact same condition applies to each case, varying only in the value. This is, in fact, a good example of when you probably SHOULD use GOTO over IF-ELSEIF-ELSE, if speed is an issue.
