Condition-Block Syntax

Condition-Blocks are control blocks that decide which part of the SIS files are skipped during installation.

Condition-Blocks can include the following:

Conditional-Blocks (including language dependent file blocks) are evaluated at the end of the installation.

Syntax

IF (condition)
    package-body 
[ ELSEIF (condition) 
    package-body 
] 
[ ELSE 
    package-body 
] ENDIF

The square brackets enclose conditions within the Condition-Block statement that are optional.

Note: It is advisable to put conditions within the square brackets.

The Condition-Blocks can be used to ensure that the SIS file installs appropriate binaries for the target platform. For example: 

IF FPHARDWARE=0
"\epoc32\release\gcce\urel\myapp.exe"-"!:\sys\bin\myapp.exe.exe";
ELSE
"\epoc32\release\gcce\urel\myappVFP.exe"-"!:\sys\bin\myappVFP.exe";
ENDIF

Example

The following example illustrates the usage of Conditional-Blocks within a PKG file: 

; PKG file to illustrate conditional blocks
