APL2C: Difference between revisions

[[Control structure]]s in APL2C are written using the <syntaxhighlight lang=apl inline>∇</syntaxhighlight> character, which is not used for [[defined function|function definition]] because this is initiated with editor interaction rather than source code. All control structures consist of an opening <syntaxhighlight lang=apl inline>∇</syntaxhighlight> followed by an expression, and closed with <syntaxhighlight lang=apl inline>∇</syntaxhighlight> alone. For example, the following structure doubles <syntaxhighlight lang=apl inline>X</syntaxhighlight> if it's less than 3.
