Print#

The Print block is used to print values or text in the Print Console or VEX IQ Brain’s screen.

A single purple block with rounded edges that reads 'print Hello' with a right-facing arrow icon on the right side.

All reporter blocks will be printed as integer (whole) numbers by default. Use the Set Print Precision block to adjust the number of decimal places printed.

All new projects begin with the screen cursor at row 1 column 1, and at row 1 on the Print Console.

By default, the Print block will remain on the same row for any subsequent print commands. By expanding the Print block to show and set cursor to next row, this will move the cursor to the next row after printing.

Important: The Print block will not print anything to the Brain screen unless it is expanded to and set cursor to next row or followed by a Next Row block.

A single purple block with rounded edges that reads 'print Hello and set cursor to next row' with an arrow icon on the right side.

Any block that returns a value can be used in the Print block.

Choose which device to use.

A notched, purple block with rounded edges that reads 'print VEXcode on Brain' with an arrow icon on the right side. A dropdown menu is open, showing the options 'Brain' and 'Console,' with 'Brain' selected.

In this example, the robot’s current rotation will be printed to the IQ Brain.

Two connected, notched blocks with rounded edges. The first block, in yellow, reads 'when started.' The second block, in purple, reads 'print drive rotation in degrees on Brain and set cursor to next row.'"

Set Cursor#

The Set Cursor block is used to set the cursor location for Print blocks on the IQ (2nd gen) Brain’s screen or Controller’s screen.

A notched block in purple that reads 'set cursor to row 1 column 1 on Brain.'"

The Set Cursor block accepts a range for row of 1 to 20 and a range for column of 1 to 80.

Inside the loop, there is a gray comment block with the text 'Print the current timer on the Brain,' followed by a purple block that prints the timer in seconds on the Brain and sets the cursor to the next row. Below that, another gray comment block says, 'After 1 second, clear the value and reset the cursor.' The next blocks include a yellow 'wait 1 second' block, a purple 'clear all rows on Brain' block, and a final purple block that sets the cursor to row 1, column 1 on the Brain. This configuration loops continuously, displaying the timer value, waiting, clearing the screen, and resetting the cursor.

Next Row#

The Next Row block is used to set the print output cursor on the Print Console, IQ (2nd gen) Brain’s screen, or Controller’s screen to the next available row.

A notched purple coding block with the text "set cursor to next row on Brain" written in white. There is a dropdown menu on the right side labeled "Brain.
