``` x,y=10,20 ``` which are equivalent, or in a more descriptive manner: ``` LET numberA,numberB,stringA$,stringB$ = 1,2,"hello","goodbye" ``` One, extremely handy functionality of assignments is that in the case of assignment of multiple variables, if there are fewer values after the = operator than the variables before it, then all the remaining variables get initialised to that specific value. The following line: ``` a,b,c,d,e,f=0 ``` will create variables **a**, **b**, **c**, **d**, **e** and **f** and set them all to **0**. Similarly the following line: ``` a,b,c,d,e,f=10,20,30,1 ``` will assign **10** to variable **a**, **20** to variable **b**, **30** to variable **c** and **1** to variables **d**, **e** and **f**. In the example above we could remove altogether line 10 and instead enter: ``` 15 a,b=10,15 ``` which is functionally equivalent to both lines 10 and 15! Finally, assignments can be made cumulative with the use of special combination operators as seen in the table below: | Assignment Operator | Numeric Variables | String Variables | |---|---|---| | += | Increases variable by the value assigned | Concatenates string variable with the string assigned | | −= | Decreases variable by the value assigned | – Not Applicable – | | **\***= | Multiplies variable by the value assigned | Replicates the string variable as many times as the numeric value assigned | | /= | Divides variable by the value assigned | – Not Applicable – | | ^= | Raises variable to the power assigned | – Not Applicable – | | **&**= | ANDs variable with the value assigned | – Not Applicable – | | \|= | ORs variable with the value assigned | – Not Applicable – | | ^\|= | XORs variable with the value assigned | – Not Applicable – | | <<= | Shifts left the variable as many positions as the value assigned | – Not Applicable – | | >>= | Shifts right the variable as many positions as the value assigned | – Not Applicable – | | **MOD**= | Performs a MODulo operation on the variable with the value assigned | – Not Applicable – | *Table 2 – Accumulation assignments* This allows us to be a bit more terse when writing a program by reducing the amount of text we have to type, making for some more readable code. Consider the following example: ``` 10 LET a=10 15 LET b=15 20 LET c=a 30 LET a=a+b 40 LET b=b+c ``` Using the information we've just learned, we can rewrite it to use multiple assignment statements as well as cumulative assignment operators like so:
