Lightswitch

Lightswitch is an esolang created by User:Infinitehexagon about Light switches and the state of light switches. It only uses one keyword; toggle.

Syntax

Light switches cannot have a custom name. When giving a value to a lightswitch, it's name must be a p followed by the lightswitch number. The lightbulb number always starts at 0 and it should be in a numerical order for each new lightbulb called. eg
p0 toggle p0
toggle p0
This program calls lightswitch p0 and gives it a value of I , or 1.

Built-In Keywords
