GLOSSARY OF TERMS - CX-Supervisor User Manual
ADO stands for Active Data Objects and is data access technology which
uses OLE-DB to access data sources in a uniform way e.g. MS-Access
databases, MS-Excel spreadsheets and Comma Separated Variable files.
A logic operator used to interrogate Boolean type points. AND returns
'TRUE' if all arguments are 'TRUE'. An example of AND is that if a is a
statement and b is a statement, AND returns 'TRUE' if both a and b are
'TRUE'. If one or both statements return 'FALSE' then AND returns
'FALSE'.
A software program that accomplishes a specific task.
applications are CX-Supervisor, CX-Server and Microsoft Excel. CX-
Supervisor and its development environment allows the creation and
testing of new applications through a Graphical User Interface (GUI).
Words, phrases, or numbers that can be entered on the same line as a
command or statement to expand or modify the command or statement
within the CX-Supervisor script language. The command acts on the
argument. In essence the command is a verb, and the argument is the
object of the verb. An example of an argument in CX-Supervisor is
"DDETerminate(channel)" where DDETerminate is a command
within the script language, and channel is the argument upon which the
command will act.
An old standard, defining a set of characters. Officially using only 7 bits
allows definitions for only 127 characters, and does not include any
accented characters.
The representation of an image stored in a computer's memory. Each
picture element (pixel) is represented by bits stored in the memory. In CX-
Supervisor a bitmap image can be installed as a single object.

meaningful designation. Examples are:
