How to save and recall a variable

[kickingvegas]

From the Casual main menu, selecting (z) Variables gives you options to manage the life-cycle a variable.

For example if you wish to create the variable foo with the value 18.43, do the following:

1. Enter 18.43 to the stack. It should be at the (1:) position.
2. From Casual main menu, select (z) Variables > (s) Store (1:)…
   You will be prompted to enter a variable name. Enter foo.

To recall foo do the following:

1. From Casual main menu, select (z) Variables > (r) Recall…
   You will be prompted to enter a variable name. Note that completion is supported, so pressing the <tab> key will provide a set of choices which can be narrowed down.

Actions to support managing the life-cycle of a variable are all provided by the Variables menu. Of note is the ability to persist variables so that they can be recalled across restarts of Emacs.
