-Since version 1.2, multiple statements can be written in one line using the statement separator character ('':''). This, in combination with the line concatenation character allows you to write multi-line ''IF ... THEN'' blocks: 
- 
- if x = y then ~ 
- print "the numbers are equal" : ~ 
- print "whatever else here" : ~ 
- eq = 1 ~ 
- else ~ 
- print "the numbers are not equal" : ~ 
- eq = 0 
-  
-The above is technically a single line in **XC=BASIC**. 
- 
-Note that no other characters are allowed after the ''~'', not even a whitespace!
