Execution flow

1. Sequential execution: top to bottomCopy Anchor Link

Actions in the same block execute one after another, from top to bottom.

tell "Step one"
tell "Step two"
tell "Step three"

The messages appear in order: “Step one”, then “Step two”, then “Step three”.

Think of preparing a meal: wash the ingredients, chop them, then cook them. The order matters.

2. Group actions with { }Copy Anchor Link

Use a pair of braces, { }, to group actions that should execute together:

{
  tell "First action"
  tell "Second action"
}

The block acts as a unit. Its actions execute in order before execution continues outside the block.

3. ConditionsCopy Anchor Link

Kether supports “if…otherwise…” logic:

if CONDITION then {
  ACTIONS_WHEN_TRUE
} else {
  ACTIONS_WHEN_FALSE
}

For example:

if check money >= 100 then {
  tell "You have enough money"
} else {
  tell "Not enough money"
}

Execution proceeds as follows:

1. Evaluate check money >= 100 to get true or false.
2. If true, execute the actions inside { } after then.
3. If false, execute the actions inside { } after else.

Wrap the actions after then and else in { }, even when a branch contains only one line.

4. Nesting: blocks inside blocksCopy Anchor Link

A block can contain another if and another pair of { }:

if check money >= 100 then {
  if check level >= 10 then {
    tell "You have enough money and a high enough level"
  } else {
    tell "You have enough money, but your level is too low"
  }
} else {
  tell "Not enough money"
}

The outer condition determines which branch to enter. If that branch contains another if, its condition is evaluated in the same way.

Remember: actions run top to bottom, conditions select a path, and blocks group actions.
