IF...THEN...ELSE blocks don't seem to work

[byronpendason]

My code:

PRINT "What is your name, adventurer?"
INPUT "> "; name$
PRINT "Greetings, "; name$; "!"
IF name$ = "Byron" THEN
    PRINT "Welcome, Byron, the greatest hero of all time!"
ELSE
    PRINT "Greetings, "; name$; ". Not the hero I was expecting, but I guess you'll do."
END IF

I get an error about no viable alternative, as shown in the screenshot provided.

As an update, I went through your examples and discovered that in order to use if block statements, you must use BEGIN after THEN and ELSE. The following modification of the above code works:

PRINT "What is your name, adventurer?"
INPUT "> "; name$
IF name$ = "Byron" THEN BEGIN
    PRINT "Welcome, Byron, greatest hero of all time!"
ELSE BEGIN
    PRINT "Greetings, "; name$; ". Not the hero I was expecting, but I guess you'll do."
END IF

So, while this makes sense, it's not QBasic compatible because QBasic lacks the BEGIN statement.
