Using Variables in Action and Data Type Definitions

You can include string variables and environment variables in action and data type definition files.

Using String Variables in an Action

A string variable definition remains in effect from the location of the definition to the end of the file. There are no global string variables for the database.

If a string variable and environment variable have the same name, the string variable has precedence.

To Define a String Variable

Use the syntax:

	set variable_name=value

Variable names can contain any alphanumeric characters and underscore (_). Each variable definition must be on a separate line.

For example:

set Remote_Application_Server=sysapp
set Remote_File_Server=sysdata

To Reference a String Variable

Use the syntax:

	$[{]variable_name[}]

For example:

EXEC-HOST			$Remote_Application_Server
CWD					/net/${Remote_File_Server}/doc/project

Using Environment Variables in Actions and Data Types

Reference an environment variable using the syntax:

	$[{]variable[}]. 

The variable is expanded (replaced by its value) when the database is loaded. If a string variable and environment variable have the same name, the string variable has precedence.

For example, this execution string prints a file with a banner containing the login name.

EXEC-STRING lp -t$LOGNAME %(File)Arg_1%
