Variable References

Some string attributes in the AWM model support the use of variable references. Referenced variables can be defined dynamically as part of a string and can reference AWM properties, environment properties, and certain static variables. See the table below for more information. If AWM properties are referenced, values are resolved at run time and preferably taken from the "previous tool" execution context pool, if available.

Variable references are only resolved by the following attributes:

Attributes Static Value and Default Value of the relationship Tool has Input Parameter. See Relationship: Tool Has Input Parameter for more information.
Attribute New Static Value of the relationship Parameter Override. See Parameter Override for more information.
Attribute Name Physical in File Descriptor. See File Descriptor for more information.
Attribute Value in Simple Enabled Condition. See Enabled/Visible Condition for more information.
Attribute Value of the relationship Application Options Have Custom Attributes for the attributesAUTO_PARSE, and INITIAL_PARSE. See Relationship: Application Options Have Custom Attributes for more information.
Attribute Label of an Action Descriptor. See Action Descriptor for more information.
Attribute Parmfile used in the Master Configuration file. See Master Configuration for more information.
Attribute Table View Id in Action Descriptor and Element List Structure. See Action Descriptor and Element List Structure for more information.
Attribute Table View Label in Action Descriptor and Element List Structure.
Attribute Default Value in Property. See Property for more information.
Attributes Title, Description and Help Text of modeled dialogs. See Open Modeled Dialog in the AWM function package for more information.
Open Modeled Dialogs Attributes UI Category, UI Form, UI Help Text, Label, UI Tab, UI Tool Tip in modeled input dialogs. See Input Dialog in the AWM function package and Tool Has Input Parameter for more information.
Attribute Message of the AWM function package tool Validate Value. Only the properties defined in the corresponding modeled dialog are available for resolution in this case.

References can be defined by using the Start Reference and End Reference symbols (default "&" and ".") which are defined in the application options. See Application Options for more information. It is possible to define a value containing several references as well as static characters. The following table shows the syntax of all variables that are available:

Variable/Syntax	Description	Example
%<env-var>	Reference to an environment variable on the client’s local operating system.	&%PUBLIC. = C:\Users\Public
<property ID>	Reference to a property in the execution context.	&PROP_WorkspaceFilename. = /MyProject/MyFile.txt
numelements	Number of elements being processed in the current context. In single processing contexts the resolved number is always 1. In mass processing contexts it is the number of sub-contexts. See Mass Processing Overview for more information.	&numelements. = 4
wspath	Path of the active Eclipse Workspace on the client’s local machine.	&wspath. = C:\workspaces\workspace1

Examples

The following example show the definition of a dynamic file path.

Attribute value of Name_Physical (File Descriptor):

Reference	Resolved Value
&%PUBLIC.\MyCache\&PROP_FileName.	C:\Users\Public\MyCache\MyFile.txt
&userid..SOURCE(&PROP_Membername.)	USER123.SOURCE(MEMXYZ)
