Cells and assignment

Orientation

Use = to alias a cell, := to create a fresh copy, and ~= to replace a cell's value in place. === asks whether two names still share a cell.

Read this chapter with RatCalc open. Predict the result before running an example, then change a single part and run it again. That small loop of prediction, execution, and inspection is the fastest way to make RiX syntax feel like a language rather than a table of symbols.

A worked example

Runnable RiXRun cell

x := 5 y = x x ~= 9 x === y

The final line is the displayed value; the earlier lines set up the experiment. Keep the setup visible so you can tell whether a name, a cell, or a collection is being reused when the expression changes.

Read the result

Deep-copy forms (::= and ~~=) matter when nested collections must not share children.

Try a second value of your own. When an advanced feature depends on files, JavaScript, or extension registration, RatCalc explains the concept but does not grant browser permissions implicitly. Use the detail pages and the help panel to connect this experiment to the broader language rules.

Return to the overview when you need context, or continue to the next sibling lesson for a focused variation. Collection chapters also end with method help that includes signatures and examples.
