Given a list of variable names {x1, x2, x3, ...}, preserve the value of those variables in a new set of variables {prev_x1, prev_x2, prev_x3}.
Use this template to prevent a template from affecting the variables of a page it is transcluded in.
Who knows what will happen if you nest this.
Pair with Template:Load.
Example:
| Input | Output |
|---|---|
{{#vardefine:x|1}}{{#vardefine:y|2}}{{#vardefine:z|blue}}
{{Save|x|y|z}}
{{#vardefine:x|1a}}{{#vardefine:y|2a}}{{#vardefine:z|red}}
{{#var:prev_x}}, {{#var:prev_y}}, {{#var:prev_z}}
