A programmable controller includes a parameter manager to manage a parameter including an operation mode setting indicating whether an operation mode of the programmable controller is an active mode or a debug mode, and a character string data outputter to output character string data based on a message output command included in a program in the programmable controller. The message output command includes a first argument specifying whether a command is to be executed when the operation mode is the active mode or to be executed when the operation mode is the debug mode. The character string data outputter outputs or does not output the character string data to a preset destination, based on a result of a comparison between the operation mode setting and the first argument.
