Scriptol/If Control Structure

Common syntax
For a conditional process, the statement is a "if" keyword, followed by a boolean expression, a list of statements to execute or no, depending of the condition, and the "/if" keyword.

If x = 5 print "equal" /if

Introducing an alternative by the "else" keyword: when the condition is false, another list of statements may be processed.

If x = 5 print "equal" else print "not equal" /if

One-line structure
When the body of the structure is just one statement, and not another structure, the syntax may be shortened to only a single line.

If x = 5 print x

If the statement is not a command as "print", "break", "continue" etc..., the "let" keyword is required.

If x = 5 let y + 1

Composite if
The structure may be extended into a more powerful construct that is both an "if" and a "switch case" structure, even more advanced than the C counterpart since you can test any type of variable.

if x   = 5: print "equal" > 5: print "more" else print "less" /if
