Parameters are placeholders in archive files. When installing the product, the Installer assigns target computer-specific values to the parameters. There are two types of parameters that supply these values:
Specified internally either by the product being packaged or the target operating system.
Used to customize the installation. External parameters are usually called client parameters.
The following archive files can contain parameters:
Every package created with the Software Management Packager contains default values for the client parameters used. If a product requires nondefault values for its parameters, an accompanying parameter product must be installed on the target computer before the product is installed.
All parameters are indicated by a Dollar sign ($) followed by the parameter name in parantheses.
Example:
$(SxpWinDir).
If an SXP product contains a string of the previously mentioned form $(…), either within path names or in configuration files, this string must be preceded by a further Dollar sign ($). When the Installer detects a string of the form $(…), it automatically assumes that this is a parameter and tries to resolve the parameter by its value.
