Conditional statement with yes block only structure:

Conditional statement with yes and no blocks structure:

Conditional statement has two or three components:

• condition statement
• yes block
• no block (optional)

Condition statement type can be:

• variable condition
• statement condition
• compare condition

The line 'esverdad ?', is the condition line. The esverdad is the condition statement, of variable condition type, and the question mark '?', is Tyl symbol for conditional statements.

In this code:

The characters combination '\t' is Tyl code for TRUE, and is replaced by the symbol 'ｔ', which is Tyl symbol for TRUE. The caret '^', is Tyl code for end statement, and is replaced by 'ᐤ'. Tyl needs an end statement, to know where the yes block ends.

The above code will look like:

If there is only one statement in the yes block, it is posible to write the yes statement right after the condition:

The line esverdad ? print 'Si', is called a one line conditional statement, and is good for short conditional statements.
