The [[_CONTROLCHR]] statement can be used to turn OFF control character attributes and allow them to be printed.
{{PageSyntax}}
: [[_CONTROLCHR]] {OFF|ON}
{{PageDescription}}
* The [[OFF]] clause allows control characters 0 to 31 to be printed and not format printing as normal text characters.
::For example: '''{{text|PRINT CHR$(13)|green}}''' 'will not move the cursor to the next line and '''{{text|PRINT CHR$(9)|green}}''' 'will not tab.
* The default [[ON]] statement allows [[ASCII#Control_Characters|Control Characters]] to be used as control commands where some will not print or will format prints.
* '''Note:''' File prints may be affected also when using Carriage Return or Line Feed/Form Feed formatting.
* The QB64 IDE may allow Alt + number pad character entries, but they must be inside of [[STRING]] values. Otherwise the IDE may not recognize them.
