## Description
|
||
|
|
|
||
|
|
* ELSE is used in a IF block statement to cover any remaining conditions not covered in the main block by IF or [ELSEIF](ELSEIF).
|
||
|
|
* [CASE ELSE](CASE-ELSE) covers any remaining conditions not covered by the other CASE statements.
|
||
|
|
* ELSE can also be used as a false comparison to a true IF statement when a condition will only be true or false.
|
||
|
|
* Other [IF...THEN](IF...THEN) statements can be inside of an ELSE statement.
|

## Example(s)
|
||
|
|
|
||
|
|
One line IF statement
|
||
|
|
|
||
|
|
```vb
|
||
|
|
|
||
|
|
IF x = 100 THEN PRINT "100" ELSE PRINT "Not 100"
|
||
|
|
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
Multiple line IF statement block
|
||
|
|
|
||
|
|
```vb
|
||
|
|
|
||
|
|
IF x = 100 THEN ' code executed MUST be on next statement line!
|
||
|
|
PRINT "100"
|
||
|
|
ELSE PRINT "Not 100"
|
||
|
|
END IF
|
||
|
|
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
To alternate between any two values (as long as the value after ELSE is the same as the condition)
|
||
|
|
|
||
|
|
```vb
|
||
|
|
|
||
|
|
IF a = 3 THEN a = 5 ELSE a = 3
|
||
|
|
|
||
|
|
|
||
|
|
```
