A standard program

For the logic a recipe does not describe.

Creating it

Create a program of kind standard. It starts empty, as a list of lines.

The instructions

Add lines and fill in their arguments — the set is in Programs. There is no syntax to learn and no way to write a line that does not parse.

Variables and conditions

Conditions are built from variables. Where you need to refer to something in the project — a tool, a recipe, a position — use the generated variable rather than a number: it survives edits that a number does not.

Calling it from a recipe

A palletising program can call a standard program at defined moments — before a pick, after a drop, at the end of a layer. That is how a cell does something extra without you writing the palletising itself.
