Net.Data Reference Guide

Common Constructs

The following syntax elements are used frequently in the language construct descriptions.

Variable Name

Purpose

One or more names, each additional name concatenated by a period (.). A name is an alphabetic or numeric string beginning with an alphabetic character or underscore and containing any combination of alphabetic, numeric, or underscore characters.

Syntax

   +-.--------+
   V          |
>>-----name---+------------------------------------------------><
 

Variable Reference

Purpose

A variable reference returns the value of a previously defined variable and is specified with $ and (). For example: if VAR = 'abc', then $(VAR) returns the value 'abc'. Variable references are evaluated during run time. When a variable is defined for an EXEC statement or block, the Net.Data runs the specified action when it reads variable reference.

The variable that is referenced must be defined in the Net.Data macro before being references. If the variable is not defined, an empty string is returned.

Syntax
