SECTION 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.
The 'Type' column refers to the types of script and expression the function can
be applied to. 'All' refers to both expressions and scripts. 'Scr' refers to scripts
only. 'OP' refers to Object and Page scripts only.
