5.1 Expression handling, expressions, and functions

This group of commands manipulates value handling constructs in source code. For example, you can select an expression (using the Versor selection), and turn it into a variable, so that you can re-use the same value. Likewise, you can convert an expression into a function, so that you can call it elsewhere.

• Convert to variable: Convert selection to variable Given a selection containing an expression, this sets up a variable initialised to that expression, and replaces the original expression with that variable.
• Convert to function: Convert selection to function This takes the selection, defines a new function just before the one containing the selection, and replaces the original selection with a call to the new function.
• Surround with call: Surround selection with call This wraps the selection with a call to a function.
• Create function: Create function for call This creates a new function to suit the function call around point
• Remove call: Remove surrounding call This removes the function call surrounding point.
