InternalDependence Section of info.sxp

InternalDependence section of the info.sxp archive file can have the following entries:

Archive_name_1 operator_1 version_1	optional
:
Archive_name_n operator_n version_n	optional

The InternalDependence section describes dependencies on other products on the target computer. In this section, you can make any number of entries describing dependencies. All entries in this section are optional.

Archive_name

Specifies the name of the package as it appears in the Packager's product archive (maximum 32 bytes). Note, that on DOS and Windows 3.x only up to eight bytes are supported.

Operator

Specifies, in connection with a version number, when to install the product. The following operators are permitted:

=	Installation, when this version of the product is installed.
>	Installation, when a later version of the product is installed.
<	Installation, when an earlier version of the product is installed.
>=	Installation, when this version or a later version of the product is installed.
<=	Installation, when this version or an earlier version of the product is installed.
!	Each of the above operators can be negated by prefixing it with an exclamation point (!).

When the exclamation point (!) is used as operator, a condition is regarded as true, even if the product is not installed on the target computer. Use the exclamation point (!) operator if the installation is not to be performed when the two versions are compared.

Example: prod_a !<= 2000 specifies that the product is not installed if version 1000 to 2000 of prod_a is installed on the target computers. If prod_a is not installed or if the version is > 2000, the new product is installed.

The operator must be enclosed in blanks (spaces)!

Version: Indicates the version of a product with dependencies (range: 1000 - 9999).

Example: Specifies that an MS Office program can only be installed on Windows NT 4.0 or newer

#InternalDependence#
Word >= 7000
PPoint >= 5000

An Excel product can be installed only if the products Word and PPoint are already installed with the specified or a newer version on the target computer, that is, only on Windows NT 4.0 or newer. The Excel product is created as a delta product (using the automatic method) based on previously generated products Word (Version 7000) and PPoint (Version 5000).
