#change is a ZZT-OOP command that lets you change all instances of a given element with another element.
Syntax
#change [<source color>] <source element> [<target color>] <target element>
In both cases, the color argument is optional. While the element argument is supposed to be mandatory, an empty string is treated as equivalent to a board edge. Providing an invalid element name will throw a Bad #CHANGE error.
Bugs/Quirks
- ZZT has a limit of 150 stats. If you try to #change statless elements into statful ones, it will only produce them up to that limit - the remaining elements will be turned to Empties instead.
- Due to a bug, errors thrown by #change do not stop execution of the command! This can cause uninitialized memory to be used as the element and/or color arguments - causing unexpected behaviour and, potentially, crashes.
