# CRT

# Description
This statement sends data directly to the terminal, even if a PRINTER ON statement is currently active. It takes the general form:
CRT|DISPLAY expression {, expression..} {:}
expression can evaluate to any data type. The CRT statement will convert the result to a string type for printing. Expressions separated by commas will be sent to the screen separated by a tab character.
The CRT statement will append a newline sequence to the final expression unless it is terminated with a colon ":" character.
# Note
As expression can be any valid expression, it may have output formatting applied to it.
A jBASE BASIC program is normally executed using buffered output mode. This means that data is not flushed to the terminal screen unless a newline sequence is printed or terminal input is requested.
This makes it very efficient. However you can force output to be flushed to the terminal by printing a null character CHAR (0). This has the same effect as a newline sequence but without affecting screen output.
Older versions may use DISPLAY in place of CRT.
An example of use is as:
FOR position = 1 TO 5
DISPLAY @(position, 10) : position
NEXT position
