===== SWAP  =====

===== SYNTAX =====
     SWAP var1, var2

==== PURPOSE ====


The ''SWAP'' command is used to swap the values of two variables. In practice, 
the contents of the first variable are assigned to the second and vice versa, 
in a single operation.

The ''SWAP'' command makes code more concise and readable by avoiding the use 
of a temporary variable for swapping. Since swapping elements is a fundamental 
operation in many sorting algorithms, such as bubble sort, it is important
that it is an efficient operation. Infact, actually performs a similar operation 
at the assembly level, more efficiently and hidden from the programmer.

The ''SWAP'' operation can only be used with variables of the same
bit width (in case of numeric type) or the same type (if strings).



==== EXAMPLE ====
    a = 42 : b = 84
    AT a, b
    PRINT a, b


==== ABBREVIATION ====
