Change

#change is a ZZT-OOP command that lets you change all instances of a given element kind with another element.

Syntax

#change <source kind> <target kind>

An empty string is treated as equivalent to a board edge. Providing an invalid kind 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.
