CHAPTER 4
CX-Supervisor Script Language
This chapter describes the CX-Supervisor script language syntax. It provides a detailed definition of
the syntax of CX-Supervisor scripts that drive project, page and object actions, and CX-Supervisor
expressions as used by objects and scripts. In conjunction with the script functions and methods
described in Chapter 6, the CX-Supervisor script language provides a very powerful, compiled, fast
and full featured programming language.
The following table describes the script language syntax at a glance.
Function Name Function Type Type Remarks
&, |, ^, <<, >> bitwise operators All Applies bitwise expressions
(objects) statement OP Specifies an object name for
modification or test.
(points) statement All Specifies a point name for modification
or test.
+, -, *, /, %, =, ++, -- arithmetic operators All Applies arithmetic expressions.
<, >, <=, >=, ==, != relational operators All Applies relational expressions.
AND logical operators All Applies logical expressions.
CALL statement All Call a subroutine
DO LOOP WHILE UNTIL
EXIT DO statement Scr Script segment to be repeated
FALSE Boolean state Scr Applies Boolean expression.

FOR statement Scr Script segment to be repeated
IFTHEN ELSE\ELSEIF
ENDIF statement Scr Applies a test to a script.
OR logical operators All Applies logical expressions.
NOT logical operators All Applies logical expressions.
REM statement Scr Remarks on line or lines of script.
RETURN statement Scr Stops sequential execution of script.
