PRINT Keyword

Syntax

PRINT $expression

Parameters

• $expression – Any valid BASIC expression whose evaluated value will be printed to the server log.

Description

PRINT evaluates the given expression and writes its string representation to the application log (using the log::info! macro). It does not send any output back to the user; it is primarily a debugging aid for developers to inspect variable values or intermediate results during script execution.

Example

SET total = 42
PRINT total          ; logs "42"
PRINT "User: " + user_name   ; logs "User: Alice"

When the script runs, the values are written to the server’s log file and can be viewed in the console or log aggregation system.

Implementation Notes

• The keyword always returns UNIT (no value) to the script.
• It runs synchronously and does not affect the dialog flow.
