\"\"\"\" \"\"Place a true<\/em> or false<\/em> sign in the grid at a random location, according to programming. The choice of sign can be imposed or random.<\/p>\n

If the instruction operates in isolated mode, the designer randomly selects an intersection whose row and column are empty of any sign (no true<\/em> , no false<\/em> , no Boolean).<\/p>\n

\"\"<\/p>\n

Maximum number of instruction executions. It is recommended to end programs with a final instruction:\u00a0 PLACE false,<\/em> to be repeated until resolved. Therefore, on the last instruction, you can set a high maximum, which will never be reached, such as 1000.<\/p>\n
